Dealing with compilers that pretend to be GCC

Hi Paul,

Paul Eggert <eggert@cs.ucla.edu> skribis:

Right.  But how would you write feature tests that would check (1)
whether the GNU C language is supported, and (2) whether GCC plug-ins
are supported?

That’s the problem I’m trying to solve.

Thanks,
