xm-sysv4.h: Provide definitions/prototypes for host environment

functions for which no definitions or prototypes are provided in
any currently included gdb or host environment header files.
For SVR4, this currently includes malloc and realloc, which cannot
be portably prototyped in any gdb include file.

+
+	* buildsym.h:  Remove obsolete variable file_stabs.
+
+	* Makefile.in:  Move place where configure merges in host-
+	and target-dependent fragments later, so the latter
+	can override (say) GNU_MALLOC.
+	* config/mh-rs6000:  Use system malloc.  Otherwise, I
+	ended up with *two* incompatible versions of malloc
+	(functions in libc would call the malloc in libc).
+	I assume this is a shared library problem.
+
+	* remote.c:  Fix (presumed) typo.
+	* objfiles.c:  Use xmalloc/xrealloc instead of
+	malloc/realloc (since the latter are no longer declared).

+	Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
+	[Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
+	* rs6000-xdep.c: Improvements to fetch_inferior_registers() to
+	handle individual registers.
+	* tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
+	correctly in case it wasn't cached yet. (A problem showed up
+	after fetching individual registers.)
+	* buildsym.c: Disable type_synonym_name's type name overwriting
+	in cases it is unnecesary. rs6000 portation doesn't use
+	type_synonym_name, and it used to nullify type names
+	* xcoffread.c: to handle g++'s typename abbreviation, fill in a
+	type's name as soon as space for that type is allocated.
+	* xcoffread.c: ignore a section's lineno information if it is
+	not `.text'. (In rs6000 bfd portation integration, skipping over
+	`.pad' sections are ignored since it was in machine independent
+	part of the code. Thus, a problem of fake sections with invalid
+	lineno information arised.)

+	* rs6000-tdep.c: make function_frame_info() work whether or not
+	reading from a core file.
+	* tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
+
+	* infrun.c. main.c, printcmd.c. symtab.c:
+	More changes from IBM for rs6000.
