I wanted to whitelist platforms. linux is diverse, but often very well supported.
For all others we can say yes/no with certainty after testing.

How do gcc48 and dependencies get exempted so they can build with the system

Please use the gcc-inplace-math option. That should cut out most of that


Thanks, but all it seems to do is eliminate mpfr and mpcomplex.

Almost half of the deps are indirect. Perl is required for building gcc-c++, so there seems to be no getting rid of it. I'm content to live with it as-is, as long as I can build a useful gcc package with GCC 4.4 for a couple more years. At that point, RHEL 6 will be fading from existence and we'll be talking about how deprecated GCC 4.8 is...
