CI: Update Linux runner to 24.04

termhook.asm: help debugging by running an int3 in I_AM_DEAD_loop

CI: Force lower case when unzipping (#176)

Sometimes DOS packages can have upper or mixed case filenames that Linux
unzip doesn't recognise as needing downcasing.

Import textual fixes from fd-nls [closes #174] (#175)

commit 01c4ad0a496797e74fccee2e5ae61244f8e4e641

    Fix typos in the original English files for many projects.

add /D option to FOR command to look for directories instead of files matching the "set" file specifiers

e.g. to list all directories: FOR /D %a in (*.*) DO ECHO %a

use head instead of stack for recursive delete, avoid stack corruption on really nested directory structure

increase size of heap from 6KB to 8KB for build.sh also

DBCS: handle DBCS for "mkdir /p" and "rmdir /s"

(cherry picked from commit b231e93802276bf67357a05a1a191a5696b8df6b)

patchsize should attempt to patch FreeCom build regardless of compiler that builds tool which may not match compiler that built exe being patched.

dir.c: allow 21.7303 to return NC, ax=0 to mean supported (EDR-DOS)

EDR-DOS returns NC, AX = 0000h from 21.7303. This was incorrectly
detected as "not supported" here. CF unchanged and AL = 00h is
the typical error return, albeit CF unchanged AX unchanged has
also been observed (on dosemu2 + lDOS + SRDISK).

Reference on the correct "unsupported" return:
https://sourceforge.net/p/freedos/mailman/message/59128382/

Incorrect interrupt list entry:
https://fd.lod.bz/rbil/interrup/dos_kernel/217303.html

set CY before calling 21.71 or 21.73 DOS functions (LFN, FAT32)

Between the current lDOS kernel (which doesn't support 21.73),
SRDISK, and dosemu2 revision 6a2f4f527 the return from 21.7303
somehow is with both Carry Flag and AX preserved. This makes the
DIR command think that the call is supported when it isn't.

The proper check is to call with CY set before the call.

increase size of heap from 6KB to 8KB

(size based on discussions on FreeDOS mailing list, TODO validate actual size used and see if can be semi-automated to ensure adjusted up or down as actually required)

loadhigh.c: put maximum array sizes in defines and check for overflow

loadhigh.c: no record UMB region if excluded UMCB is Z and empty

loadhigh_prepare: support lDOS S MCB of type 30h (excluded UMA)

loadhigh_prepare: accept empty MCBs (memory block size zero)

Broke LH on lDOS, reference: https://github.com/FDOS/freecom/issues/166

loadhigh_prepare: on MCB allocation error do not leak memory

fix recursive remove dir

mcb_walk.c: try querying UMB link state even if not on DOS 5+

Current lMS-DOS still reports its version as v4.00 but does fully
support a DOS-managed UMA. As of today lMS-DOS also supports the
SHELLHIGH= directive. Like FreeDOS's this is implemented using
the 21.4B80 extension. Although the internals differ, the outside
observable behaviour is the DOS executable loader allocates both
the environment and the process memory block into the UMA, if
there are free UMBs. However, unlike LH the UMB link state is not
enabled once the control flow is passed to the application. That
means an environment block in a UMB isn't reachable when walking
the MCBs without regard to proceeding past the first UMCB.

The MCB walker is used in FreeCOM's init to validate the
environment block passed to it upon its startup. Reference:
https://github.com/FDOS/freecom/blob/cede733377c454cb93e9038d476582f0d1fcbf0a/shell/init.c#L238

If this check fails, then the shell will prompt for the position
of its executable as follows. This patch makes the MCB walker
enable the UMB link even if the reported DOS version is below 5,
allowing it to find the environment block's UMCB and avoiding
the prompt.

Failed to load the strings resource into memory, the location
pointed to in %COMSPEC% seems to be invalid. Please specify another
location of FreeCOM to try to load the strings from, e.g.:
C:\COMMAND.COM
or just hit enter to cancel to load the strings.

ico files are binary, don't convert linefeeds

ver.c: try 21.3306 true version call, if zero then use 21.3000 version

ver.c: strip 21.33FF trailing blanks, append linebreak

Some kernels such as RxDOS, EDR-DOS, and lMS-DOS do not include a
linebreak at the end of the string, while FreeDOS does (an LF).

ver.c: detect support of 21.33FF using dx=0, instead of OEM id

fixes #159 - display DOS minor version with 2 digits

NLS update Turkish

build: correct file dependencies in make files

CI-build: extend test OW cross-compile to 1.9 and 2.0 versions

cleanup code to be more transparent

doesn't use static symbol name in prototype or parameter name, it is confusing

fix cross-compilation build of fixstrs.exe

the format of the response file depends on the compiler used, which is not generally correct for cross-compilation
the program has been modified to define the file format via a command line option, making the file creation transparent and defined to be correct for currently used tool

build: minor corrections in make file

reformat make files for consistency

CI-build: add upx build option

next fix string --> strings

CI-build: add Open Watcom test cross-compile on Windows/Linux/Mac OSX

fix string --> strings

build: fix OW support for cross-compile on Mac OSX

build: fix clean scripts

watcom: fix backward compatibility with OW 1.9

build: fix cross-compile setup for gcc and Open Watcom

gcc doesn't support compact memory model, configuration handle this special case by generating appropriate message, now it happens only for fixstrs.exe (in strings)
Open Watcom can be run from Windows or Linux or DOS, only necessary is define WATCOM env.variable and add host OW binaries on the PATH, all other is handled by make files

git: update .gitignore file to exclude more file extensions

build: rename response file to consistent name with .rsp extension

watcom: fix source code for Open Watcom Linux build

update version in git, 0.87 - unreleased next version

build: separate fixstrs.exe and critstrs.exe host(native) build

rename macro FIXSTRS_BUILD to COMPACT_MODEL
add new macro UTILS_BUILD for host(native) build
DOS build is not changed
toolchain configuration should be control by UTILS_BUILD macro to switch between host(native) and cross compilation
16-bit DOS memory model is control by COMPACT_MODEL macro

update release 0.86 docs

enable recursive make directory (md /p dir\subdir\...)

delete echoto.bat in strings when running clean.bat

avoid leaking findfirst handle if path too long

enable recursive remove dir (rd /s)

build: add ptchsize as native build for cross-compilation

ptchsize is build tool (used by FREECOM build) and also DOS target tool
now
in tools (DOS tools included in distribution) is DOS version
in utils (host native tools used by FREECOM build) is host OS version

build: remove redundant rules

handle echo...bat batch file more transparent way

correct header files references

build: rename macros to be more transparent

build: fix build by tlib and response file (Borland tlib)

fix special handling of (&) character for Windows cmd.exe shell
fix (+)add character handling

remove useless second list for librarian, now handled in echolib.bat

asm: remove some MASM residual directives

build: add message for echoto.bat arguments overflow (#132)

fix if exist path command checking for "path command" instead of path

Build: Add missing prefix
