I just tried it ...

root@kerravon2-pc:/home/kerravon/w2kshare# ./lintest.exe abc "d e f" ghi
welcome to pdptest3
main function is at 08048294
allocating 10 bytes
m1 is 0804FFB0
allocating 20 bytes
m2 is 08050000
stack is around FFA5115C
printing arguments
argc = 4
arg 0 is <./lintest.exe>
arg 1 is <abc>
arg 2 is <d e f>
arg 3 is <ghi>
root@kerravon2-pc:/home/kerravon/w2kshare#

... works fine already.

If it didn't, I would have reused the code I already
use for MSDOS.

BFN. Paul.
