OK, but how about if we fix that by syncing non-Gnulib-using code with 
Gnulib-using code? This should be relatively easy. Something like the 
first attached patch, say. If there's still interest in 32-bit binutils 
this would be a better approach. (If there's not, then we don't have to 
install any patch. :-)

PS. While looking into this I noticed a grep portability bug in a couple 
of 'configure.ac's, fixed in the 2nd attached patch.

PPS. I couldn't get a 32-bit version of binutils-gdb to build on Fedora 
x86-64, even without either of the attached patches. See the 3rd 
attached file, which is a compressed log of my attempt to build. Here's 
the first part of the failing output:
