[Description]
Checks whether a character is a foreign uppercase.

[Explanation]
isfrgnupper returns nonzero if <I>c</I> is a non-Greek foreign uppercase letter (0xC0 to 0xDE except
0xD7), otherwise it returns zero.
It is a relatively small inline function which is implemented using GNU C smart macros.
