FWIW, I'm also running into issues where this commit made compilation of one source file run forever. Previously, compilation of the file took 47 seconds, now it doesn't finish in 10+ minutes.

If you want to have a look at that case in case it's an issue different from the others, it's available at https://martin.st/temp/glew-preproc.c, try building with `clang -target x86_64-w64-mingw32 -c -O2 glew-preproc.c`.
