When attempting to compile the svn-fetched 4.8.0, I get the following error
during configuration:

The configure uses the following:

./configure CC="gcc -D_FORTIFY_SOURCE=0" --build=x86_64-apple-darwin11.4.2
--prefix=/Applications/madsdk --with-gmp=/Applications/madsdk
--with-mpfr=/Applications/madsdk --with-mpc=/Applications/madsdk
--enable-languages=c,c++,fortran --disable-multilib

This is running on OS X Lion (10.7.5).
