FreeBSD has supported printing backtraces for years. The API is the same
as on Linux, the only difference is that libexecinfo must be linked as a
seperate library. Since the last FreeBSD version with backtrace support
(FreeBSD 9.3) went out of support some time ago unconditionally enable
the printing.
By default minizip uses fopen64(), fseek64() and so on. Those may not
be defined on all system, especially the BSDs. While FreeBSD already
has a special case, for example OpenBSD hasn't. Work around this by
forcing minizip to use fopen(), fseek() and so on everything that's not
Linux or Windows. This is not 100% correct, it may prevent the usage of
ZIPs lager than 2GB on Solaris and other rarely used systems. But I
doubt that anyone has such large ZIPs with assets, they would likely hit
other internal limits.
In the future Quake II should use off_t instead of int were applicable.
With that we could set -D_FILE_OFFSET_BITS=64.
This change is based upon a patch send by @devnexen in pr #279.
There's no need to duplicate machine independent parts of the client
initialization and the main loop for every platform.
While at it remove the nearly empty unix.h header and move Windows
main() into an own file. Not both platform have the same basic layout.
While building the wrapper as a console application is completely fine
there're some advantages by creating a "real" Windows GUI Application:
* Console applications always spawn an annoying console window.
* Windows GUI applications seem to have a much lower chance to trigger
my new best friend, the Windows Defender. As a console application
quake.exe triggered every time I started it, as Windows GUI
application not only once.
Use WinMain() instead of wWinMain() because MinGW doesn't know about
the later and it doesn't matter anyways.
libSDLmain.a has to be linked and must run anyways. So there's no need
for us to reinvent the wheel, just rely on SDLs process setup, argument
parsing, message handling and so on. As a nice side effect this may fix
some strange bugs related to message handling and argument parsing...
Before we can ship the softrenderer in the default install we'll need to
clean up the cvars. Currently the softrenderer is using the gl_* cvars
which is confusing.
Commit 883781c selected these paths for all OSs, but when linking to
a system copy of OpenAL for Linux distribution binaries we want the
normal OpenAL in /usr.

Highlights are:
- Since MSYS2 is much more unixlike than our old build environment we
can remove most Windows specific hacks from the Makefile.
- MSYS2 has an package manager, the build environment can be updated
by "pacman -Syu" just like an ordenary Arch Linux installation.
- Parallel builds are now working.
- git is integrated into the build envirment.
- zlib is now linked as a dynamic lib.
After this commit the old bild environment will no longer work! The
latest version must be downloaded and extracted to C:\MSYS2. Get it
here: https://deponie.yamagi.org/quake2/windows/build/
still no 3D rendering, but in theory it should be able to load models,
bsps etc, just not render them yet.
also moved/copied md2.c and sp2.c to gl/ and gl3/ because they use
renderer-specific types
the arguments were not used anyway, and returning true/false is clearer
than returning -1 (for error) or sth else (which has no deeper meaning
anyway).
Also:
* PrepareForWindow() can now return -1 if there's an error
* suppress some warnings in Makefile
* fix error for building ref_gl.dylib on OSX
the problem is that sdl2-config --libs apparently includes shit that's only
useful for the executable, but not dlls, like linking against SDL2main and
libmingw32 and setting -mwindows
Furthermore I forgot to add -lopengl32 and -shared to the ref_gl Windows
LDFLAGS.
If someone really want's overwrite OSTYPE on Windows it's much easier to
just alter one line in the Makefile than supporting setting it through
the command line.
