I have just performed a clean install of cygwin after cleanly 
reinstalling my laptop. I thought I would take the opportunity therefore 
to test this. Interseting results!

$ echo "#include <stddef.h>" | gcc -mno-cygwin -E -
# 1 "<stdin>"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "<stdin>"
# 1 "/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/include/stddef.h" 1 3 4
# 158 "/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/include/stddef.h" 3 4
typedef int ptrdiff_t;
# 220 "/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/include/stddef.h" 3 4
typedef unsigned int size_t;
# 332 "/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/include/stddef.h" 3 4
typedef short unsigned int wchar_t;
# 2 "<stdin>" 2

So I'm picking up i686-pc-cygwin

But...

$ gcc -mno-cygwin -print-search-dirs
install: /usr/lib/gcc-lib/i686-pc-mingw32/3.3.1/
programs: 
=/usr/lib/gcc-lib/i686-pc-mingw32/3.3.1/:/usr/lib/gcc-lib/i686-pc-ming

:/usr/lib/gcc/i686-pc-mingw32/:/usr/lib/gcc-lib/i686-pc-mingw32/3.3.1/../../../.

686-pc-mingw32/3.3.1/:/usr/lib/gcc-lib/i686-pc-mingw32/3.3.1/../../../../i686-pc
-mingw32/lib/:/usr/lib/gcc-lib/i686-pc-mingw32/3.3.1/../../../i686-pc-mingw32/3.

/:/lib/:/usr/lib/i686-pc-mingw32/3.3.1/:/usr/lib/

I'm picking up mingw32 here.... strange!

Cygcheck attached..
