Re: gcc throwing an internal error only on HP-UX ?

[Harri Pasanen <harri dot pasanen at trema dot com>]

Well, I just tested with gcc version 3.0.2 20011002 (prerelease),  and the 
same problem (PR 4351) remains.

I'm hoping that someone working on gcc at HP would step forward and correct 
this thing ;-).
