as.h.
* as.h: Include alloca-conf.h first. Include ctype.h, string.h, strings.h,
stdlib.h, unistd.h, sys/types.h, fopen-bin.h, fopen-same.h, as suggested by
autoconf test results.
[BROKEN_ASSERT]: Don't include assert.h.

* gasp.c: Include config.h, stdlib.h (if HAVE_STDLIB_H). Don't include host.h.
(malloc) [NEED_MALLOC_DECLARATION]: Declare.
* messages.c: Include as.h first. Include errno.h only if HAVE_ERRNO_H. If
HAVE_VARARGS_H and not __STDC__, undefine HAVE_STDARG_H. Set NO_STDARG and
NO_VARARGS as appropriate.
* doc/Makefile.in (srcdir, INSTALL, INSTALL_PROGRAM, INSTALL_DATA): Use
autoconf @-substitutions.
* as.c (main): Move a inside the #if 0 block which uses it.
* ecoff.c (current_stabs_filename): Make const.
* frags.h (frag_align_pattern): Declare.
* gasp.c (new_file): Cast isp to long, and use %ld to print it.
* config/tc-alpha.h (md_operand): Add cast to void.
(alpha_do_align): Declare argument types.
(tc_get_register): Declare.
(alpha_frob_ecoff_data): Declare.
* config/tc-alpha.c: Include <ctype.h>.

(line_comment_chars): Remove /* from descriptive comment.
(tc_get_register): Remove unused local reg.
(tc_gen_reloc): Don't bother to compare unsigned to zero.
(s_base): Correct warning to actually print register number.
(md_begin): Remove unused locals retval, lose, and i.
(alpha_fix_adjustable): Move default case inside switch to avoid
warning.
(load_symbol_address): Remove unused locals reloc_addr, p, sym,
and addend.
(emit_byte_manip_r): Declare types for all arguments.
(emit_extract_r, emit_insert_r, emit_mask_r): Likewise.
(emit_sign_extend, emit_bis_r, s_proc): Likewise.

Recognize --help and --version.
* config/tc-ns32k.h: Define TC_NS32K.
* doc/as.texinfo: Document all of the target-independent command
