[gentoo-dev] f77 is now just plain old fortran in preparation for gcc4

[Travis Tilley]

the fortran-enabling logic in the gcc ebuilds + toolchain.eclass will 
now be controlled by the fortran USE flag instead of f77. This is some 
very ahead-of-time preparation for gcc 4.0, which doesnt support f77 as 
a gcc lang, but instead supports f95 (and may soon change the gcc lang 
option to plain old fortran as well). I've updated all profiles to also 
set fortran in USE by default, but some non-gcc ebuilds still use f77 to 
enable support, so I havent removed f77 from these profiles.

This may or may not have been important enough to merit an announcement 
on gentoo-dev, but I've learned my lesson about making invasive changes 
without an announcement of some sort. ;p


by the way, if anyone's masochistic enough to play with gcc4, I have an 
ebuild in my devspace you could use:
http://dev.gentoo.org/~lv/gcc-4.0.0_alpha20041024.ebuild

I havent yet updated it with the needed dependencies for enabling 
fortran95, or any other such nonsense... it was made just to test which 
ebuilds no longer compile with the yet-again-stricter gcc 4.0. have fun 
breaking your systems ;p
