OK, before this duck thing gets a bit out of hand, back to a more 
day-to-day-like problem:

I would need to test whether the compiler accepts “-OMG” 
AND
I would need a way to test whether the compiler is specifically GCC (not clang, 
not icc) between 3.2.0 and 3.4.2

as I would need to disable -OMG on GCC version 3.2.0 to 3.4.2 because of user 
report of miscompilations and/or buggy code there.

How do I do that the autoconf way with the tools I have in 2.69 and the macros 
of the autoconf archive? I already do have code for testing the version 
numbers, it’s the specific GCC/clang and -OMG tests which are a bit more 
problematic.

Best,
  B.
