Glibc also implements many non-standard functions found in BSD, SysV
and other Unixes, making porting code from those systems to glibc
easier.  This is not fundamentally a bad thing.  I agree that
inventing extensions of their own is bad.

Well, given that we both consider C++ dubious from the get-go...
Apart from that code that relies heavily on gcc extensions isn't all
that common.
