FSF GCC has several issues on Mac OS X, this might be one of them ?
The regular builds of GDC instead uses the Apple GCC, e.g. gcc-5363.

The Apple build does --with-arch=nocona --with-tune=generic
for i686, the platform has been arch i686 since Mac OS X 10.4
(Intel Darwin version 7 and earlier instead used arch i386)
Probably doesn't make a huge difference, just like you say.

Beyond the fact that you can install it to a different prefix,
you can get the tarball version at http://dgcc.sourceforge.net/
