[Fergus Henderson]

Estimated hours taken: 0.25

Fix a bug reported by Bas De Becker <basde.bakker at pica.nl>.

runtime/machdeps/regtest.c:
	Move #include statements after the global register variable
	declaration, to avoid problems on systems which define
	inline functions in the system header files.
