Why are you using both -m32 *and* a cross-compiler?  If you're running 
64-bit Cygwin and need to make a 32-bit Cygwin program, use the 
cross-compiler.  Passing -m32 to the 32-bit Cygwin compiler shouldn't be 
necessary.

I wouldn't expect -m32 to work for Cygwin since it's not like other 
64-bit *ixes where 32-bit programs are expected to work side-by-side 
with 64-bit ones.  So, while any problem in -m32 handling could 
doubtless be fixed, there isn't a whole lot of incentive to do it. 
Cross-compiling fits the two-separate-platforms nature of the situation 
better.
