GCC 4.x fails to build

[Evan Ward]

I'm trying to install a non-Apple version of GCC because a program I'm
trying to install uses nested functions, and the version of GCC Apple
ships has compiling nested functions disabled. The following is the
output from version 4.3, but I get pretty much the same error from
versions 4.2, 4.1, and 4.0.

Has anyone had success compiling GCC? Do I need to do anything special?

Thanks,
Evan
