The following patch cleans up most of the failures seen in the collation
test. It does not fix the transform failures and libstd tests.
2012-10-10 Liviu Nicoara <lnico...@apache.org>
Various fixes:
* tests/localization/22.locale.collate.cpp: removed unused
macros, corrected assertions and their formatting. (c_xfrm):
corrected use of safety buffers. (make_test_locale): used
rw_create_locale, used the whole portable character
set. (check_libc): split code, restored previous locales after
test. (check_NUL): hard-coded positions of NUL characters.
