It's this code in Embed.t:
--8<---------------cut here---------------start------------->8---
# XXX DAPM 12/2014: ExtUtils::Embed doesn't seem to provide API access
# to $Config{optimize} and so compiles the test code without
# optimisation on optimised perls. This causes the compiler to warn
# when -D_FORTIFY_SOURCE is in force without -O. For now, just strip
# the fortify on optimised builds to avoid the warning.
my $ccflags = ccflags();
$ccflags =~ s/-D_FORTIFY_SOURCE=\d+// if $Config{optimize} =~ /-O/;
--8<---------------cut here---------------end--------------->8---
It clearly didn't expect the symbol definition getting preceded with
"-Wp," (I still don't know where that is coming from). However, just
commenting out the line doesn't produce any warnings or erros from gcc
either, so I don't even know what problem it was trying to solve.
Regards,
Achim.
