I'm adding this paragraph to tm.texi:

For each predicate function named in @var{PREDICATE_CODES}, a
declaration will be generated in @file{insn-codes.h}.


I'm updating the Copyright notice of gcc.texi (that of tm.texi already
has 2001) and checking them both in along with the rest of the patch.

I don't recall any such problems, but then, my experience with
compilers other than GCC is quite limited.  I suggest that we wait
until we find some compiler that can't cope with this before we trade
cleanliness and coding standards-compliance for potential portability.
