PS: Sorry about the delay. I looked at the paths when I got home and, sigh,
I had used the wrong path in my search before.

I am not familiar with cygwin, but that looks wrong for -m32. 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.
