Perl and Cygwin do not exactly play together at the moment, but I haven't been able to track down where that happens. Perl configure recognizes FORTIFY_SOURCE=2 proceeds to integrate that knowledge into Config_heavy.pl. For whatever reason it decded to use "-Wp,-D_FORTIFY_SOURCE=2" to do that (which works just fine). But when compiling something through ExtUtils::Embed in the just built perl that option suddenly ends up as just "-Wp," and hangs up the compiler. If I rename the defined symbol to "FORCIFY_SOURCE" then it stays in the call to gcc, so it's specific to that symbol.
I think that's happening somewhere in ExtUtils, but I'd like to ask if maybe there is some magic going on from the Cygwin / gcc side to remove that definition?
