Subject: Fix filestuff.c build error if RLIMIT_NOFILE  not defined.
X-Git-Tag: gdb-7.7-release~308
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f9b0da3d5833ad5f809422f3084b0ef8fa5c5762;p=external%2Fbinutils.git

Fix filestuff.c build error if RLIMIT_NOFILE  not defined.

Not all systems supporting getrlimit also support RLIMIT_NOFILE
(Eg. All LynxOS systems appear to be lacking support for this).
So check its existance before using it.

gdb/ChangeLog:

        * common/filestuff.c (fdwalk): Add "defined(RLIMIT_NOFILE)"
        preprocessor check.
