The function is in the library libmingw32.a.  Since the gcc specs file
automatically adds -lmingw32 to every link invocation, it should always
be included.  What version of gcc?  What version of mingw-runtime?  What
is the output of the above command with -v added?

You might be able work around this by adding an explicit -lmingw32 to
the end of the command, but this should not be necessary.
