But the question I pose here is with respect to GNU extensions, either they're 
enabled or not... seems incongruous to have -std=c99 for clang but -std=gnu99 
for gcc.  I believe pkgsrc should at least be consistent (one way or t'other).

From the clang getting started page:

In any event, various cflags/cxxflags tend to be set for compiler-specific needs.
