It would be helpful if I had the option to remove this flag from XQuartz. </PRE> </BLOCKQUOTE> Patch #1 is designed to maintain status-quo following the removal of -fno-strict-aliasing from CWARNFLAGS and does not require subsequent patches. It's a 'global' setting. Patch #2 is designed to maintain status-quo, but making it easy for various parts of the code to enable optimization if appropriate. It was later altered for XQuartz, which could have been done through a subsequent patch. The alternative to patch #2 is for components to append -fstrict-aliasing to override -fno-strict-aliasing. </BODY> </HTML>
