Right, we don't want no steenking worms around here ;-)

So I'd like to ask people who have access to various non-standard 
platforms to compile and run the small test program below and report the 
results to me.  (Please do NOT post to the news group; write to me 
directly, and I will summarize.)

Environments to which I don't have access, and which are therefore more 
interesting: OS/2, Linux/DOSEmu, Caldera's DR-DOS with its own DPMI 
server, 386Max.

Please report the version of the OS and the DPMI host with the results.

Thanks in advance.
