I think this is the default and I have it: cc1plus: warnings being treated as errors I have seen this kind of failure in the past, but in this case I am unable to find a work around.

--- Comment #4 from dominiq at lps dot ens dot fr 2008-01-14 14:36 --- Just for the record I have also found the warning in the make log of rev. 129958. The only difference I had with the previous builds was the use of '--enable-maintainer-mode'. I am now tring with '--enable-maintainer-mode --disable-werror'. Now I have checked on the gcc lists that I have been hit couple time by 'cc1: warnings being treated as errors' (see for instance http://gcc.gnu.org/ml/fortran/2007-11/msg00254.html). has there been any change on the cc1plus options recently? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34780

If you don't specify it, -Werror is turned on for the main development trunk. However it defaults to off for release branches and final releases. The specific files which get -Werror are controlled by the Makefiles. Why do I have '-Werror' while building libstdc++-v3? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34780
