Is there any way to get more fine-grained control over which languages and
libraries are installed with GCC? Portage lets you decide whether you want to
build the Java compiler, but C++, Ada, Fortran, and Objective C are built by
default, even though many people do not need all these languages. Perhaps some
new USE flags?
c++ is required by certain core packages early on (ie. groff, iirc).
fortran is required by many of the mathematic and even multimedia packages.
still researching if anything uses objective c
java is alreay optional in the gcc ebuild (USE=-java and it won't be built).
this leaves ada, which afaik, isn't used by anything.
so possibly an objc use flag, and probably an ada use flag.
cant do much with this during release
