Reintroduce CSTD, which allows a Makefile to specify the precise dialect
of C in which the program or library is written.
Note that this is *not* intended to be used across the whole tree. It
is intended to be used for individual libraries or programs which use
specific language features which the compiler must know about in order
to produce correct warnings at high WARNS levels.
