Shur thing. The snippet is a GREP of the sources - there is no valid 
continuity between those lines :) I just wanted to point out the amount 
of constructs scattered around, and thus the necessity to replace the 
ENTIRE source by a non-portable variant if I was to put in into a C-lib.

But may be Johnathan suggestion would work - I'll check it if I get some 
help with that.
