+Subject: [PATCH] libtool: handle the -pthread{,s} options for g++
+Newsgroups: gmane.comp.gnu.libtool.patches
+Date: Thursday 28th November 2013 14:18:05 UTC (over 4 years ago)
+
+As we are forced to pass -nostdlib to g++ for linking, this option
+expectedly disables the effectiveness of passed -pthread flag - so
+add the -lpthread explicitly to $deplibs to link correctly.

+
+* build-aux/ltmain.in (func_mode_link): Explicitly add -lpthread
+flag into $deplibs when -pthread is passed (for g++ only).
