No. We're preparing for the unicode RTL.

Part of that was changing string -> shortstring and pchar -> ansichar.

In some rare places I changed string to ansistring in preparation of
unicodestring, in this case it was misplaced since it was a var argument. 
I added an overloaded version, which should fix the compilation error.
