Ethan,

As a crude test, I did a mass replace of "unsigned int" by "signed int" 
in the pdf.trm file and the datastirngs.dem demo seems to run fine. 
 (The conversion to a float in the PDF_xxx() routines is where the 
wrap-around of the number occurs.)...  There are a lot of occurrences of 
"unsinged int" throughout the software, aren't there?
