STRICT_WARN (i.e. -pedantic) was added to all the frontends (except Ada)
many years ago.  So this comment about use of extensions requiring
gcc-2.95 might be obsolete.

I suspect you may be able to cross-build all of non-ada GCC with any ISO C
compiler right now (I haven't tried it though since I don't have access to
an appropriate system.)
