Hi

Has anybody got the LWP multithreading package working 
with djgpp 2.03 ?  The package and example programs compile,
but running example1 produces following results (screen dump follows):

The program should alternately print MAIN and PROC n as main and 4
threads execute. As you see, my compilation only executes the main
thread. After keypress the problam should kill the threads and exit,
mine gets a SIGSEGV.

I am running Win98, after experiencing problems with Win2k and make...
djgpp version is 2.03, gcc is 2.95.2 and the lwp package is 2.0 from
jtlwp20.zip.
