Just a guess: your 64-bit windres is generating a 64-bit .res file that the 
32-bit g++ can't grok.  Look at 'windres -h'.  There's a "-F" == "--target" flag 
that can specify a target type.  I would try adding "-F pe-i386" after the "-O 
coff" on your command.  If windres doesn't accept both -O and -F, try leaving 
off the "-O coff" and just specify the -F flag and value.  Good luck.
