I seem to keep having problems with my C compilers.  First I
had Laser C, but I wanted ANSI so I bought Lattice 5, but it
was quite buggy, so now I am using GNU C.

Anyway, I was using evnt_timer/evnt_multi to wait for a certain
amount of time in Lattice C, then I would poll the serial port
to see if anything had arrived...well, this worked fine for
Lattice with a wait count of 10 (low-count).  Well needless to
say, this doesn't work fine for GNU C.  Any amount of time over
0 is pathetically slow.  I mean I set it to 100 for one particular
instance and I would still be waiting for it to time-out if I
hadn't rebooted.  What's the deal?  Does GNU use seconds instead
of milli-seconds for its timer calls?  I really need to have this
work so I can look for bar-code reader input...it works in Lattice!!

Any help is greatly appreciated.
