[patch] Tweeks for HP/UX 10.20 gcc -Werror

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

The attached fixes a build on HP/UX 10.20 configured with 
--enable-gdb-build-warnings=-Werror (not ,-Werror).  It isn't trying to 
fix any bugs.

I've checked it in as obvious.

	Fix -Werror problems.
	* somsolib.c (som_solib_add): Use core_addr_to_host_pointer.
	(som_solib_desire_dynamic_linker_symbols): Compare integers with
 	zero not NULL.
	* hp-psymtab-read.c (hpread_call_pxdb): Make parameter constant.
