Summary: .MOD files: Consider removing the time stamp Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: bur...@gcc.gnu.org At http://gcc.gnu.org/ml/gcc-patches/2011-01/msg02012.html Simon Baldwin wrote: Strict build environments do binary comparisons of files across gcc builds. Writing the current timestamp into a Fortran .mod file leads to false positives from such environments. Omitting the timestamp removes these false positives. That change was in Google's internal GCC - and is now pushed to the Google branch in SVN. One should consider to apply the patch also to the trunk
