Great, I'm glad you found a workaround for the problem.  Still, it's
odd that I did not see it.

Earlier you made the point that you would like to use "gcc -m32".  So
it turns out that the i386 and amd64 versions of libgmp-dev are now
co-installable and with both installed, you can indeed compile in
either 32- or 64-bit mode!
