wineg++ -v test.cpp

<cstdlib> and <cmath> of the C++ standard library fail to find <stdlib.h> and
<math.h> (with #include_next) when using wineg++ since Wine 3.21.

This seems to be because wineg++ (built with --prefix=/usr) now adds -isystem
/usr/include to GCC's command line. This changes the order directories are
searched (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70129).

winegcc.patch

Cannot reproduce with debian packages, the prefix is differently set up there.

Does this patch help?

Yes, that patch fixes it. Thanks!

/usr/include is back to its original position in the search path.

It seems to be back with Wine 6.6 and Manjaro.

using wineg++ and including cstdlib causes a cstdlib:75:15: fatal error:
stdlib.h: No such file or directory
