Preventing inlining of intrinsic functions

[Vortex]

Here is a small header created by LD Blake as a start in avoiding optimizer bugs
in Pelles C. It tells the compiler to treat affected code as functions rather
than inlining them into the main code.

Please feel free to add to this and post updates for this header, to help others
on the forum.
