(x86 assembler optimization disabled for now because it
requires the new .cfi_* directives that is not supported
by base system binutils).

These are two of the three files that have non-trivial differences from
the vendor branch. minigzip.c is the third, but there were no changes
from ZLib 1.2.1 to ZLib 1.2.2 in that file.
The rest of the files I intend to get reverted back to the vendor
branch (with cooperation of cvsadmin@).
PR: i386/76294
just breaks the prototypes for gzseek() and gztell() when an application
defines HAVE_UNISTD_H before including <zlib.h>. z_off_t was always
long for compiling zlib, but was sometimes off_t for compiling
applications, e.g., Ethereal 0.7.5.
This "fix" preserves bug for bug binary compatibility. z_off_t should
be off_t for everything, but zlib doesn't support off_t being longer
than long, so using the correct type without fixing zlib's internals
would at best break binary compatibility. This "fix" also make the
namespace problems for HAVE_UNISTD_H no worse than hundreds of other
namespace prooblems in zconf.h. I'll wait for a new release of zlib
for proper fixes.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
