If you can see an easy fix I can try that. Else I’ll probably just revert and let you investigate.
I appear not to have Cygwin, and no other gcc is not in my path. I just rely on the one that comes with GHC.
After reverting, here’s what happens when I compile foo.c (trace below). The invocation of cc1.exe looks rather different
C:/code/HEAD/inplace/mingw/bin/gcc.exe -v foo.c
Using built-in specs.
