            Bug ID: 61013
           Summary: Option parsing difference between < 4.9 and 4.9
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: andres at anarazel dot de

In gcc 4.8 a binary compiled with "gcc -g3 ... -g" would include the extended
debug information (e.g. macros), while in gcc 4.9 the second -g seems to lower
the debug level.
That's obviously not a critical issue, but it's annoying enough because several
buildsystems add -g internally, often after the user supplied CFLAGS, making it
harder to build with a sufficient amount of debuginfo.
