Clean up compilation warnings coming from PL/Perl with clang-12~
clang-12 has introduced -Wcompound-token-split-by-macro, that is causing
a large amount of warnings when building PL/Perl because of its
interactions with upstream Perl. This commit adds one -Wno to CFLAGS at
./configure time if the flag is supported by the compiler to silence all
those warnings.
This back-patches commit 9ff47ea41 into out-of-support branches,
pursuant to newly-established project policy. The point is to
suppress scary-looking warnings so that people building these
branches needn't expend brain cells verifying that it's safe
to ignore the warnings.
