All, with the work from Jennifer Yao and John Marino we can now update the locale support on FreeBSD to the level of DragonFly. Results of this work can be found on the results list. Here my small addendum to make it work on FreeBSD. Is this ok for trunk? (Given that the work from Jennifer and John are committed before stage3?) TIA, Andreas 2015-11-12 Andreas Tobler * acinclude.m4 (GLIBCXX_ENABLE_CLOCALE): Change locale implementation from darwin to DragonFly. * configure: Regenerate. * config/os/bsd/freebsd/ctype_configure_char.cc: Improve locale support, do it the same as DragonFly. * config/os/bsd/freebsd/os_defines.h: Add fine grained C99 defines.
