I agree with DJ, lamentably the standard was designed for things like 
tolower(getch()) where the parameters match 100%.
But Robert pointed a problem in stricmp that I can't check right now, but I 
think is a real problem. So the bug is in libc functions that pass *(char *) 
to ctype functions and it should be fixed.

BTW: Robert, use the ucNNNN functions I added to TVision. Also, if the 
stricmp problem affects some code perhaps we can add a fixed version in 
nonansi.cc or in the "extras".
