Re: [PATCH 0/1] MR4642: configure: Use Wine includes for cross compiler checks.

[Brendan Shanks (＠bshanks)]

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.
