[PATCH 1/2] increase portability of NORETURN declarations

[Erik Faye-Lund <kusmabite@googlemail.com>]

Some compilers (including at least MSVC) supports NORETURN
on function declarations, but only before the function-name.

This patch makes it possible to define NORETURN to something
meaningful for those compilers.
