In particular, Robert once wrote that if you want to link code compiled by GCC 2.8.1 with object files compiled by GCC 2.7.x, you need to invoke 2.8.1 with -fno-exceptions -fno-rtti (obviously, for C++ only). Andrew warned about incompatibilities between PGCC and GCC. If I understand correctly, stock libc cannot be used with PGCC. Are all these still valid with the current binaries? If so, should the next FAQ release say something about these cases? I'm particularly interested to know how would these incompatibilities manifest themselves. Thanks in advance for any info.
