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.
