My program, which does a lot of integer calculations and an occasional 
printout, hangs after a time when running in a WinXP DOS-box. It hangs 
so badly that Ctrl-C can't get it out - the DOS-box must be aborted. On a 
DOS system with CWSDPMI it works without a hitch.

The only "funny" thing the program does is to read the BIOS timer variable 
using "_farpeekl(_dos_ds, 0x46c);".

I am using the "17-Nov-2003 DJGPP CVS Development Bin (djdev)", 
DJGPP Version 2.04 BETA 1 PRE RELEASE BY ANDREW COTTRELL 
BUILT WITH CVS LIBC OF 16-November-2003 

Version 2.03 gave similar results.

Any help will be appreciated.
