The problem with the SDL module is that the configure test doesn't find _main. I don't know why yet, but I have removed the kludge.
configure:1069: checking for SDL - version >= 1.2.0 configure:1190: /mnt/aphraelraid/home/peter/hack/Pike/7.4/build/windows_xp-5.1.2600-x86/smartlink rntcl -o conftest -I/usr/local/include -I/usr/X11R6/include -R/usr/local/lib -L/usr/local/lib -R/usr/X11R6/lib -L/usr/X11R6/lib conftest.c -lshell32 -lkernel32 -lws2_32 -ladvapi32 -lm -lsdl 1>&5 LIBCMT.lib(crt0.obj) : error LNK2001: unresolved external symbol _main conftest.exe : fatal error LNK1120: 1 unresolved externals CL returned error code 2.
What does the Windows SDL.h look like?

Ah-ha! From SDL_main.h:
/* Redefine main() on Win32 and MacOS so that it is called by winmain.c */
#if defined(WIN32) || defined(_WIN32) || \ (defined(__MWERKS__) && !defined(__BEOS__)) || \ defined(macintosh) || defined(__APPLE__) || \ defined(__SYMBIAN32__) || defined(QWS)
[...]
#define main SDL_main
That could have an adverse effect on the linker's ability to find "main", yes. Try this patch:

Perhaps related to the -lSDLmain and -Dmain=SDL_main magic that SDL does? Without it (in the case of a standalone app) there is is no WinMain method I believe. Does adding
-Dmain=SDL_main and -lSDLmain to the cflags respective libs help? Of course, when you link Pike itself you don't want to use SDLmain most likely (it mainly parses the command line etc).

There is no need for a "WinMain" in any of the other instances of AC_TRY_RUN, an ordinary main() works fine (as is required by the C standard). So there has to be something more to it...

Hmm. That's true.

Hm, wait a minute. That command line says
[...]/smartlink rntcl -o conftest -I/usr/[...]
but if I look at the config logs for danae in xenofarm, the commandlines say
[...]/smartlink rntcl -o conftest.exe -I/usr/[...] ^^^^
This looks very fishy. Can I see the complete config.log?

Yeah, I found it in the filesystem on aphrael. I expect the differences are due to you not using a config.cache in this build. It seems to work either way. The real problem was elsewhere (see 9928968).
