[PATCH 0/1] MR4642: configure: Use Wine includes for cross compiler checks.
C99 checks depend on stddef.h and stdarg.h. Those headers are usually shipped with compilers (and another copy of them as part of mingw-w64 for targets that use it), but some providers skip them. We use our own version during the build anyway, so we may use them for configure checks as well. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4642

On FreeBSD, this enables LLVM from ports to be used as the mingw cross-compiler: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274542 ``` $ export PATH=/usr/local/llvm17/bin:$PATH $ ./configure --enable-win64 --with-mingw=clang CC=clang CXX=clang++ CPPFLAGS=-I/usr/local/include ``` I filed [a bug report](https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274542) for FreeBSD excluding these header files, and [am starting](https://github.com/freebsd/freebsd-src/pull/915) to fix it. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4642#note_55496
