Seems all necessary code for dynamic loading was already there (dltcp.c). But when switching to icc365 there were so32dll.lib and tcp32dll.lib added to linker flags. Obviously the dynamic loaded function are not used anymore but the one from the system dlls. Removing these libs leads to an exception in strupr cause called with a const char string (FUNCTION). ICC365 seems to be more picky about such bugs that 3.08. Anyway fixed dltcp.

Needs additional testing before closing this though.
