gnulib/tests/test-getlocalename_l.c
Bruno Haible 0b6754b1de getlocalename_l-simple tests: Avoid test failure on NetBSD. 
* tests/test-getlocalename_l.c (FAKE_COLLATE): New macro.
(main): If FAKE_COLLATE is true, don't compare the result of
getlocalename_l (LC_COLLATE, ...).
* doc/posix-functions/getlocalename_l.texi: Mention the NetBSD bug.
