Yes but if C & C++ was installed after it is built, distcc/ccache could be then used to build the Fortran & GCJ & so on. Of course, there's another matter of matching gcc versions between hosts but that's just another problem that needs addressing elsewhere. Maybe I wouldn't gain much of Fortran. But if I recall correctly, gcj has a fair bit of C++ code to build. But after all, it's all purely theoretical. Unless we're going to patch gcc build system to make it more friendly. > Anyways, assuming we can't split out fortran, would you be for or against > enabling it by default? I'm good either way. Considering that it saves you like 5M? I'd rather keep it enabled. 5M won't save the day, while waiting extra 2 hours for gcc rebuild because some package needs Fortran is irritating. And I say two hours because, say, I had to enable USE=gcj earlier and now I have to rebuild that huge thing. -- Best regards, Michał Górny
