Re: [hpux] Fix build problem on hpux
This can't be right. The point is to add -D_XOPEN_SOURCE_EXTENDED
whenever we compile *on* HP-UX, not whenever we're targeting HP-UX.
This should be handled using autoconf, much in the same way as we do
for _GNU_SOURCE, since it affects the functionality made available by
the OS.
How about this instead?

* hpread.c (hpread_start_psymtab): Remove hpread_psymtab_to_symtab
declaration.
* acinclude.m4 (gdb_AC_HPUX): Define.
* config.in (_XOPEN_SOURCE_EXTENDED): Define if needed.
* configure.ac: Call gdb_AC_HPUX.
* configure: Regenerate.
