Michael,
Does the below look ok? It is to fix the IRIX 6.5 build problems. With
it applied, gdb starts but I'm not clear on testsuite results - dejagnu
fails when trying to fork. A mindless play with GDB does appear to work
though.
Its for both GDB 5.0 and the trunk.

From Michael Paddon <mmpp@esec.com.au>:
* configure.in (AC_CHECK_HEADERS): Check for <sys/user.h>.
* configure: Re-generate.
* proc-api.c: Only include <sys/user.h> when available.
(ioctl_table): Check that PIOCGETPR and PIOCGETU are defined.
* TODO, README: Update. Mention that GDB 5 needs GCC on IRIX.

* Notes for BSD/386:
To compile gdb-4.18 on BSD/386, you must run the configure script and
its subscripts with bash. Here is an easy way to do this:

GDB can produce warnings about symbols that it does not understand. By
default, these warnings are disabled. You can enable them by executing

! GDB doesn't build under IRIX6.4
