Yes, that sounds familiar.

The distinction here is that one should probably not rely on #error
within .m4 tests, since the results of the tests might not be
reliable.  But within ordinary C code, #error is fine; people with
losing compilers will simply have to look at the compilers' diagnostic
output.

Advice along these lines should be added to the autoconf manual; I'll
add this to my list of things to do.
