I also played with llvm-gcc recently and have similar problems.
I checked it like this, to see wrong installed headers into my incpath:

$ make Strip.i

$ grep ' "/usr' Strip.i | less

For me it was

# 605 "/usr/lib/perl5/5.10/i686-cygwin/CORE/perl.h"
# 1 "/usr/local/include/sys/types.h" 1 3
# 12 "/usr/local/include/sys/types.h" 3
# 1 "/usr/local/include/_mingw.h" 1 3

Bad that -I /usr/local/include overrides /usr/include.
I'll probably have to append it with -idirafter with the next perl.

In your case it looks like you use a wrong cpp.exe preprocessor or gcc
driver, maybe from llvm or mingw.
