https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203066 --- Comment #4 from commit-hook@freebsd.org --- A commit references this bug: Author: rakuco Date: Wed Sep 16 14:56:08 UTC 2015 New revision: 397068 URL: https://svnweb.freebsd.org/changeset/ports/397068 Log: Add upstream patch to fix the build with GCC 4.6, 4.7 and 4.8. runetype.h uses _Thread_local, and if we pass -std=c11 or -std=gnu11 to GCC the header expects it to be supported as part of the language and does not make it a typedef or something else. Since GCC only started supporting _Thread_local with the 4.9 series, building CMake with, say, lang/gcc (which is 4.8) fails: /usr/include/runetype.h:92:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'const' /usr/include/runetype.h: In function '__getCurrentRuneLocale': /usr/include/runetype.h:96:6: error: '_ThreadRuneLocale' undeclared (first use in this function) /usr/include/runetype.h:96:6: note: each undeclared identifier is reported only once for each function it appears in The upstream patch adds a test for _Thread_local and uses C99 instead of C11 if it fails.
