The complete list of defines for all cygwin provided compilers is given below. Is this a bug?

Is there another directory in /usr/lib/gcc/x86_64-pc-cygwin/4.8.2/include/c++ with a name that looks better than x86_64-pc-cygwin? Or is there a subdirectory 32/ in x86_64-pc-cygwin? I believe you should report this to cygwin. -- Marc Glisse
