How do I alias i686-w64-mingw32-gcc-4.5.3.exe to gcc under cygwin?

Question

I have two gcc's installed in cygwin right now: i686-w64-mingw32-gcc-4.5.3.exe and the cygwin gcc. Ill show you what I did for the sake of clarity:

$ ls -al /usr/bin/gcc*
lrwxrwxrwx 1 User None    21 Aug 16 13:15 /usr/bin/gcc.exe -> /etc/alternatives/gcc
-rwxr-xr-x 2 User None 94741 Feb 25  2009 /usr/bin/gcc-3.exe

$ ls -al /etc/alternatives/gcc*
lrwxrwxrwx 1 User None 18 Aug 16 13:15 /etc/alternatives/gcc -> /usr/bin/gcc-3.exe

$ rm /etc/alternatives/gcc

$ ln -S /usr/bin/i686-w64-mingw32-gcc-4.5.3.exe /etc/alternatives/gcc

$ gcc -v
Using built-in specs.

How do I get gcc to work?

If you need a native MinGW-w64 GCC, use a native Windows version of the compiler and call it from cmd or if you must MSYS. If not, use the Cygwin to Windows cross-compiler and encode the prefix in a Makefile/CMakeLists.txt/configure script.

Remember Cygwin != Windows, and what you are doing is cross-compiling, which in GCC land is done by calling prefixed binaries.
