             Bug #: 56067
           Summary: Removal of -Wsynth from doc didn't remove example
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: sbergman@redhat.com


Removing "@item -Wsynth" from gcc/doc/invoke.texi in
<http://gcc.gnu.org/viewcvs?view=revision&revision=97318> left behind the
@smallexample and "In this example, G++ synthesizes [...]" paragraph that
apparently belonged to -Wsynth but now make it look like they belong to the
preceeding "@item -Wsign-promo", where they make no sense (cf. the bottom of
<http://gcc.gnu.org/onlinedocs/gcc-4.7.2/gcc/C_002b_002b-Dialect-Options.html#C_002b_002b-Dialect-Options>).
