Darwin has case-insensitive filesystems
HFS+, the FS on Darwin, is case insensitive. So this patch adjusts
filename_cmp.c to ignore the casing when comparing filenames on Darwin.
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.
