--- Comment #2 from Kai Tietz <ktietz at gcc dot gnu.org> ---
Hmm, by this report I can't make much out of it.  To see the failure reported
in config.log for this test might be helpful.  I can't reproduce the issue by
building mingw-w64 based toolchain, so it seems to be something specific to
MinGW.org setup...

AFAICS might be the cause for this issue the lack of installed headers/runtime.
As you were using as prefix /mingw/local/, are you sure crt and headers are
installed in /mingw/local/mingw32/include and /mingw/local/mingw32/lib?
