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.
