HP-UX and 0713 snapshot

HP-UX and 0713 snapshot

[RDBrown]

From memory - in case someone can fix HP-UX support before the branch.

On hppa2.0-hp-hpux10.20 with the no_shared_libraries stub,
gdb linked successfully.
Running the new build on itself `hung' - using no CPU.
Sending a SIGHUP to the child gdb gave a semaphore out of sequence
message (maybe) & then the child gdb continued as normal.

On hppa1.1-hp-hpux11.00, infttrace.c fails to compile.

I'll fill this out tommorrow.

My fiddling with hppah-nat.c to close the semaphore pipes after the write and lengthen
the sleep time from 1 to 5 seconds hasn't accomplished anything .... similar behaviour.

On hppa1.1-hp-hpux11.00, the build fails because of

ptrace_wait is declared as returning int in inferior.h and ptid_t in infttrace.c. From a quick grep it seems
to be only used in inf{p,t}trace.c - so maybe pulling the declaration from inferior.h and leaving it's return type
a secret of the two declarers and users would permit a link - though the infttrace version didn't seem to be
trying to provide a return structure ...

Re: HP-UX and 0713 snapshot

[Michael Elizabeth Chastain]

I built some hppa1.1-hp-hpux10.20 about six months ago (before
no_shared_libraries went in), and I had problems running gdb
on any executable, even a static-linked "hello.c".  gdb would hang
whenever the inferior ran.

I think it would be useful to:

. pick a set of configurations to care about.  I would pick
  native hppa1.1-hp-hpux11.00 and native hppa2.0w-hp-hpux11.00 or native
  hppa64-hp-hpux11.00.  I don't know how many people in the field still
  use hpux 10.20, but I think we need some triage here.

. build and test with the gdb 5.0 release tarball.

. roll forward from there and find the last working snapshots or
  CVS checkouts.
