Why symcat.h is not included anymore?

I'm sure you know this, but for clarity's sake: symcat.h is a file
which defines macros used to allow writing source code which compiles
with either a traditional C (K&R C) compiler or an ISO C90 compiler.

The dialect of C that GCC source code is written in no longer supports
being compiled by a traditional C compiler.  You must write your code
using ISO C90.  I.e. just use the __STDC__ version of CONCAT2's
definition in your source code directly.
