I ran into something similar -- when trying to build winsup/newlib on
a Win98 machine, make will happily run for a while, and then suddenly
hang. I can kill the top few with `kill -TERM', but the lowest 2 need
to be killed with `kill -9', and then I'm back again. 

Of course, this is with *both* the new signaling code and thread enabled
code, so this evening I'll try to figure out which one may be causing
this and hopefully get a strace (don't worry, I'll trim and compress 
before sending 15MB of strace output ;-).

Corinna, could you try the same experiment please by building another
dll with --disable-threads and see what happens?

Regards,
Mumit
