Hi,
Since clang 13 each Perl or Perl XS module compile spits out a lot
of -Wcompound-token-split-by-macro warnings. E.g. p5-Net-SSLeay
produces 3882 warnings generated. You cannot spot anything useful.
The problem is burried deeply in the Perl macros and copied to
everywhere.
If we compile Perl with -Wno-compound-token-split-by-macro it gets
stored in Config.pm and is used for most modules.
$ perl -MConfig -e 'print $Config{ccflags},"\n"'
-Wno-compound-token-split-by-macro -fno-strict-aliasing
-fno-delete-null-pointer-checks -pipe -fstack-protector-strong
-I/usr/local/include
ok?
