[fpc-pascal] inline asm in fpc progran

[Michael Van Canneyt]

All Jonas wanted to say was that you didn't report on his suggestions.
How can he help further if he doesn't know the result of his previous

Giving help is in the first place diagnosing. We can't offer help if the
diagnose result is not known or incomplete.

Michael.
