[Coco] help with C problem

[Robert Gault]

Assuming there is not a BUG, looks like the error is dependent on the 
software in use. This works with Microware C in OS-9. The crucial lines 
might be found if you can get the program saved as an .a file.

_3                  (int)*s2 < 128
  ldb [6,s]
  sex
  cmpd #128
  lblt _4

If there is no equivalent to sex on your system or there is some other 
size mismatch, then maybe (int)*s2 will always be less than 128. Turns 
out that in OS-9 you get the exact same conversion with  *s2<128,
(char)*s2 < 128, or (short)*s2 <128.

If the OS-9 package is not "outside the pale" for C usage, then most 
likely char *s2 or (int)*s2 does not result in what you are expecting.
