Yup. Awhile back I went through the PG sources and made sure we
explicitly casted the arguments of ctype.h functions to "unsigned char"
if they weren't already. If anyone sees a place I missed (or that
snuck in later) please speak up!

Ditto, I saw no ctype.h usage in Manfred's code. It matters not whether
you label strcmp's argument as unsigned...
