d5a0b816a0 Bring in fix from gzip 1.3.3 to avoid crashes when processing certain corrupt 
input files:

1999-06-25  Paul Eggert  <eggert@twinsun.com>

        * inflate.c (huft_build):
        Set n to length of v, to detect improper tables.
        Don't accidentally grow j past z.

774cd1faf6 Gzip assumes 'unsigned long' is 32-bits wide and depends on this. 
One thing Gzip does is implicitly by store the size of a file into an
'unsigned long' rather than  explicitly compute the remainder modulo 2^32
(see RFC 1952 section 2.3.1 "ISIZE").  Thus an extracted file size is
does not equal the original size (mod 2^32) for files larger than 4GB.

This manifests itself in errors such as:
	zcat: bigfile.gz: invalid compressed data--length error

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are 
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Tested on: i386 (extensively), alpha

e043516d4d Check for defined(__i386__) instead of just defined(i386) since the compiler 
will be updated to only define(__i386__) for ANSI cleanliness.
