X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7d6b320b79bc7bb87a7c8985c70036e56e4c2e9f;p=external%2Fbinutils.git

[libiberty/filename_cmp] Darwin has case-insensitive filesystems

include/ChangeLog:

        * filenames.h (HAVE_CASE_INSENSITIVE_FILE_SYSTEM): Define
        on Darwin, as well as on the systems that use a DOS-like
        filesystem.

libiberty/ChangeLog:

        * filename_cmp.c (filename_cmp, filename_ncmp): Add handling of
        HAVE_CASE_INSENSITIVE_FILE_SYSTEM.
