getting glibc to compile with GCC CVS mainline

[Alexandre Oliva]

Here are patches to fix incompatibilities with the current CVS version
of GCC.

The first addresses a problem that causes GCC to reject auto nested
functions that are declared but not defined.

The second addresses a problem of trying to construct array types of
incomplete types.  Although this is well-formed C++, it's ill-formed
C, even if the type would decay to pointer to incomplete type, which
is well-formed in both languages.  There were two occurrences of this
error in glibc.
