default gcc version change when USE_FORTRAN=yes. Patches included from
http://bugs.gentoo.org/show_bug.cgi?id=318045. [1]
- Renamed and conditionalized some patches to support tgammaf function
on OSVERSION < 800023. Previously, it was included even when present
in the system math library. Also fixed name-mangling problem in the
patches. Declarations were wrapped in 'extern "C"', but the
definitions were not, causing a linker error.
- Added a patch to CMakeLists.txt to prevent cmake from changing rpath
during the installation phase. That caused libstdc++ from /usr/lib
to be used instead of the one supplied with gcc 4.5.
