[Bug c++/36334] New: typedef to function type leads to probelms

[dominik dot strasser at onespin-solutions dot com]

The attached source is accepted by gcc 4.1.2, but not by 4.3.0.
It is also accepted by e.g. the SUN C++ compiler.

I didn't find anything in the release notes why it shouldn't be accepted any
more.
