             Bug #: 50643
           Summary: Suppress cc1: warnings being treated as errors
    Classification: Unclassified
           Product: gcc
           Version: 4.5.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jg@jguk.org


My feeling is that the "cc1: warnings being treated as errors" message is not
needed. This is enabled when -Werror is specified.

I suggest to add an option to suppress that message when -Werror is enabled

-Wno-cc1-warning

Alternatively, could -Werror-quiet be added? Which simply does the same as
-Werror, but not displaying that cc1 message.

Well in 4.6 and above say which warning option is used for the error message
but that still does not help when some warnings are turned into errors.  How
can you tell the difference between a warning and an error message if the
warning is turned on by default?

differentiation between:

* error
* promoted-to-error

No visibility for the user as they appear the same in the output. Is the
differentiation needed?

Jon, judging from:

http://www.mail-archive.com/gcc@gcc.gnu.org/msg60026.html

it gives me the feeling that if you submitted a good patch and argued along the
same lines, it might get accepted (but perhaps no). But I don't think anyone
else will submit a patch on your behalf. So give it a try:
