Ran "indent", for GNU coding style; some code & comments still need fixup. 

Removed some unneeded files.

configure.in: Don't look for te-386bsd.h, which doesn't exist...

Mon Nov 23 11:00:16 1992 Ken Raeburn (raeburn@cygnus.com)
* all files: Whitespace changes for GNU indentation style, done by
GNU `indent'. Some cleanup still needed.
* configure.in: No te-386bsd.h file exists; don't try to use it.
Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
* Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
* subsegs.h: add extern to segment_info declaration.
* read.h: added extern declarations for comment_chars,
line_comment_chars, and line_separator_chars.
read.c, app.c: removed definitions of comment_chars,
line_comment_chars, and line_separator_chars.
Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
* version.c: Put conditional "const" before version_string, not
before dummy function for VMS. Now version 1.91.03.
* app.c (do_scrub_next_char): Need double-\ before `000' to show
printed rep of null character.
Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
* configure.in: i386-sysv and i386-sco use coffbfd.
* app.c (do_scrub_next_char): discard whitespace after a label.

xmalloc() - get memory or bust

xmalloc() uses malloc()
SYNOPSIS
char * my_memory;
my_memory = xmalloc(42); / * my_memory gets address of 42 chars * /
DESCRIPTION
Use xmalloc() as an "error-free" malloc(). It does almost the same job.
When it cannot honour your request for memory it BOMBS your program
with a "virtual memory exceeded" message. Malloc() returns NULL and
does not bomb your program.
