This OS has been unsupported for over 20 years. We stopped providing
macswig builds more than 20 years ago too:
https://sourceforge.net/projects/swig/files/macswig/
The required SIOUX library doesn't seem to be available anywhere
now either.
Closes#2323
Avoid using reserved identifiers such as `_DOHINT_H` (fixes#1989),
fix cases where the name doesn't match the filename, and make the naming
more consistent and less likely to collide with include guards in other
headers.
It seems too brittle to enable by default as we'd have to avoid
including any system headers after doh.h, which is hard to enforce,
but just having it enabled for one CI job should avoid uses of the
poisoned symbols from being accidentally introduced.
See #2223
Use `#pragma GCC poison` (supported since GCC 3, maybe earlier) when
compiling with GCC to help prevent direct uses being introduced for
functions which DOH provides a wrapper for.
Exit() is a wrapper for exit() by default, but SetExitHandler() allows
specifying a function to call instead.
This means that failures within DOH (e.g. Malloc() failing due to lack
of memory) will now perform cleanup such as removing output files.
This commit also cleans up exit statuses so SWIG should now reliably
exit with status 0 if the run was successful and status 1 if there was
an error (or a warning and -Werror was in effect).
Previously in some situations SWIG would try to exit with the status set
to the number of errors encountered, but that's problematic - for
example if there were 256 errors this would result in exit status 0 on
most platforms. Also some error statuses have special meanings e.g.
those defined by <sysexits.h>.
Also SWIG/Javascript tried to exit with status -1 in a few places (which
typically results in exit status 255).
Previously code in the SWIG tool didn't handle allocation failures
well. Most places didn't check for NULL return from
malloc()/realloc()/calloc() at all, typically resulting in undefined
behaviour, and some places used assert() to check for a NULL return
(which is a misuse of assert() and such checks disappear if built with
NDEBUG defined leaving us back with undefined behaviour).
All C allocations are now done via wrapper functions (Malloc(),
Realloc() and Calloc()) which emit and error and exit with non-zero
status on failure, so a non-NULL return can be relied upon.
Fixes#1901.
For example, `Char(foo)[0]` now works to get the first character
of DOH String `foo`.
Previously this gave a confusing error because it expanded to
`(char *) Data(foo)[0]` and the `[0]` binds more tightly
than the `(char *)`.
- Add support to DOH Replace for not replacing inside C comments
- Fix removing 'out' or 'ref' when these are present in C comments
in cstype typemaps.
Closes#1628
Previously generated files were not removed,
potentially breaking Makefiles using file dependencies, especially when
-Werror (warnings as errors) was used.
The commit 40bf877 fixed warnings about converting between function and object
pointers but introduced warnings about breaking strict-aliasing rules which
appear with -Wstrict-aliasing which is implicitly enabled by -O2.
Avoid these warnings as well by using an intermediate union for conversion
instead of casts trickery.
Writing a buffer to a DOH object doesn't modify so it should be const.
This allows the code using const pointers to pass them to DohWrite() without
neither the casts nor gcc warnings.

This is a preparation for moving to new DOH, since for strong typed objects we need the const_String_or_char_ptr class to implicit convert to and from String * or const char *.
