You are taking fg as a char, but printing it as an int. With djgpp, and 
int is 4 bytes and a char is either two or one (I think), depending on 
whether you're compiling as C or C++. On the sun and on bc 3.1, a char 
and an int are both 2 bytes it seems. I can't say for sure regarding the 
sun, but I know this is the case regarding bc. Anyway, just rewrite your 
printf using %c instead of %d and everything will be fine.
