--- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> 2011-09-25 19:22:14 UTC ---
Native builds of current trunk (mine is gcc-4.7-20110924 == r179148) also fail
in the same way, when configured with --disable-build-poststage1-with-cxx.  The
reason is that PR50012 (a C++ FE diagnostics bug) causes some warnings in new
code to go undetected, until someone does a build in proper C mode.

Anyway, for this PR the fix should be:
