Created attachment 474674 [details, diff] patch Soon to be released Perl 5.26 turns an old deprecation into a fatal error. Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/^\@strong{ <-- HERE (.*)}$/ at /var/tmp/portage/sys-devel/gcc-4.9.4/work/gcc-4.9.4/gcc/../contrib/texi2pod.pl line 319. Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/^\@strong{ <-- HERE (.*)}$/ at /var/tmp/portage/sys-devel/gcc-4.9.4/work/gcc-4.9.4/libjava/classpath/doc/texi2pod.pl line 314. Attached patch should fix the problem. Build tested for 5.4.0, applies also to 4.9.4 and 4.9.3, most likely also needed for earlier versions.
Luckily the failure is just ignored by the Makefile, and since this is documentation generation, the impact is limited.
Bumped patchsets and prepared ebuilds.

In any case, since this is now fixed in newest stable and in newest ~arch, it shouldnt block Perl unmasking anymore.

Thanks!

It's a rebuild of the same source. :)
Did anyone in the meantime test 4.9.4-r1 ?
