#3 Fix parser on systems where char is unsigned (Patch included
On systems like PPC and Sparc a C "char" is unsigned by default.
So it can not hold the magic EOF that's returned by fgetc() on end-of-file, because EOF usually is -1. So the parser fails to detect and end-of-file condition on such systems.
The attached patch fixes this by using "int" for the "ch" variable. (fgetc() also returns an "int" type)
