Jim Kingdon d8fc877318 * source.c (find_source_lines): Always use code that was #ifdef
BROKEN_LARGE_ALLOCA.  Do the cleanup before returning, rather than
	leaving it on the chain.  Reindent much of this function.
	* config/sparc/{xm-sun4sol2.h,xm-sun4os4.h},
	config/i386/{xm-sun386.h,xm-i386m3.h,xm-i386mach.h},
	config/m68k/{sun3os4.h,xm-news.h,xm-hp300hpux.h},
	config/ns32k/xm-ns32km3.h: Remove all references to
	BROKEN_LARGE_ALLOCA; with the above change it is no longer needed.
	* main.c, fork-child.c, many config files: Remove all
	SET_STACK_LIMIT_HUGE code; with the above changes it should no
	longer be needed.

	* symtab.c (lookup_partial_symbol): Use if and abort, not assert.
	This avoids __eprintf troubles.

	* main.c (main): Surround in #ifndef MAIN_OVERRIDE.  Move
	initialization code which needs to be called even if we bypass the
	command line stuff into gdb_init.
	* utils.c (fputs_unfiltered): Surround in #ifndef
	FPUTS_UNFILTERED_OVERRIDE.
	* Makefile.in (libgdb.a): New target.

	* utils.c: Rearrange I/O stuff a bit so that all output goes
	through fputs_unfiltered.  Use vasprintf; removes arbitrary limit
	which made %s not work with arbitrarily large strings.
	* printcmd.c (printf_command): Use printf_filtered, not
	printf_unfiltered and printf, now that arbitrary limit is gone.

/* The following text is taken from config/rs6000.mh:
* # The IBM version of /usr/include/rpc/rpc.h has a bug -- it says
* # `extern fd_set svc_fdset;' without ever defining the type fd_set.
* # Unfortunately this occurs in the vx-share code, which is not configured
* # like the rest of GDB (e.g. it doesn't include "defs.h").
* # We circumvent this bug by #define-ing fd_set here, but undefining it in
* # the xm-rs6000.h file before ordinary modules try to use it. FIXME, IBM!
* MH_CFLAGS='-Dfd_set=int'
* So, here we do the undefine...which has to occur before we include
* <sys/select.h> below.
