* Runtime problems specific to Mac OS X
** On Mac OS X, file-name-case-insensitive-p may be unreliable
The implementation of that function on Mac OS X uses pathconf with the
_PC_CASE_SENSITIVE flag. There have been reports that this use of
pathconf does not work reliably. If you have a problem, please
recompile Emacs with -D DARWIN_OS_CASE_SENSITIVE_FIXME, and file a bug
report saying whether this fixed your problem.
