I see you haven't committed this change to CVS on Savannah yet, so I'll
comment based the diff you emailed.

More importantly, this guideline is too strong as stated. For example,
although GCC does not support the __clang_major__ preprocessor variable
which specifies the Clang version, it is OK for GNU code to use that
variable, e.g., in a line "#if __GNUC__ >= 4 || __clang_major__ >= 4"
when deciding whether to use a feature that GCC 4+ and Clang 4+ both
support. I suggest replacing the above with the following, which I
expect reflects the intent better.
"The main target compiler for GNU packages in C is GCC, so don't ever
use features that GCC does not support, in a way that would cause users
to prefer using compilers other than GCC."

202s -> 2020s
copilers -> compilers
