[Description]
Translates characters to uppercase, including foreign ones.

[Explanation]
toextupper works like <A HREF="$$LINK(ctype.h/toupper)">toupper</A>, but it also converts foreign
lowercase characters (see <A HREF="$$LINK(ctype.h/isfrgnlower)">isfrgnlower</A>).
toextupper is an inline function which is implemented using GNU C smart macros, which
expands to a medium-sized code.
