Hmmmm. Interesting wrinkle.

I've tried the same build on my 735/125, and get the same results 
exactly.  If I strip the binaries, I get "main" not found.
If I build without -O2, I get zillions of undefined symbols.

This looks like a problem with HP-UX's SOM linker.  I'm using the
December-2001 patch bundle, which is the last AFAIK for HPUX-10.20.

I'm trying a build with with no debugging (-g removed) and
-O2 on.  If that fails, I'll try HP aCC.

I'll let you know...

Andrew.

PS: I'd really like DDD to work on HPUX-10.20; it's my main
platform for my day-job.
