What's the right invocation to get that? I tried some variations on:
gcc -E -mtune=generic -l/mingw64/include -l/c/home/jbm/src/emacs
-l/c/home/jbm/src/emacs/src -l/c/home/jbm/src/emacs/nt/inc src/thread.c
But always got an error:
src/thread.c:20:10: fatal error: config.h: No such file or directory

$ gcc --version
gcc.exe (Rev1, Built by MSYS2 project) 7.2.0
Thanks
