Second round of warning suppression.
Used a #pragma to kill ~170 in rpcgen code. Added GF_UNUSED to deal with a few more from macros elsewhere. The remainder are function return values (mostly context and dict calls) that really should be checked. Those would be harder to fix without real understanding of the code where they occur, so they remain as reminders. (Patchset 2: deal with older gcc that doesn't handle #pragma GCC diagnostic) (Patchset 3: fix include paths in generated files) (Patchset 4: keep up with trunk, squash 9 new warnings) (Patchset 5: six more, all in AFR) Change-Id: I29760c8c81be4d7e6489312c5d0e92cc24814b7b BUG: 2550 Reviewed-on: http://review.gluster.com/378 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
