Nitin-

I just remembered, there's one more gotcha you have to deal with
to run `gdb' on IA32 processes. `gdb' uses the shell to actually
execute the target program and, by default, it winds up using
the IA64 version of the shell. This doesn't work.

What you have to do is spcify an IA32 shell through the `SHELL'
environment variable when using the IA32 `gdb'. If all of the
IA32 programs are in the directory `/usr/ia32/bin' then the
following sommand should work:

SHELL=/usr/ia32/bin/sh /usr/ia32/bin/gdb $*
