I see this too. The compilation succeeds with 5.18.

Perhaps. But I think the fix is not in perl but in xchat-gnome.
It seems PL_memory_wrap and Perl_croak_nocontext were moved to libperl
in 5.20, so the test library needs to link with that. Adding
$(perl -MExtUtils::Embed -e ldopts)
to the compiler flags makes it pass. And xchat-gnome configuration
looks like this:
checking for perl... /usr/bin/perl
checking for Perl header files... found
checking for Perl library... found
…
checking for perl... /usr/bin/perl
checking for perl >= 5.8.1... 5.20.0
checking for XML::Parser... ok
…
checking which plugins to build... autoaway notification url_scraper
sound-notification net-monitor notify-osd perl python tcl
…
config.status: creating plugins/perl/Makefile
Attached is the patch to xchat-gnome.
Not yet reassigning to allow a sanity check on my conclusions :)
Cheers,

Description: configure.ac: fix perl header test for perl 5.20 The PL_memory_wrap and Perl_croak_nocontext symbols are now in libperl so a test program needs to link with it. Adding $($PERL -MExtUtils::Embed -e ldopts) to the compiler command line does just that.
