Mark Adler e9d5486e66 Remove K&R function definitions from zlib. 
C2X has removed K&R definitions from the C function syntax.
Though the standard has not yet been approved, some high-profile
compilers are now issuing warnings when such definitions are
encountered.

Mark Adler d0704a8201 Remove deleted assembler code references. 
The code was removed, but the builds that used the code were not
updated. This fixes that. Thanks to Adenilson and toxieainc for
the patches.

Mark Adler e13def040e Fix compilation with --solo and --debug combined. 
However this ends up not really being solo, since it has to
include external libraries.

Mark Adler 3fb251b363 Remove dummy structure declarations for old buggy compilers. 
While woolly mammoths still roamed the Earth and before Atlantis
sunk into the ocean, there were C compilers that could not handle
forward structure references, e.g. "struct name;". zlib dutifully
provided a work-around for such compilers. That work-around is no
longer needed, and, per the recommendation of a security audit of
the zlib code by Trail of Bits and TrustInSoft, in support of the
Mozilla Foundation, should be removed since what a compiler will
do with this is technically undefined. From the report: "there is
no telling what interactions the bug could have in the future with
link-time optimizations and type-based alias analyses, both
features that are present (but not default) in clang."

Mark Adler 8f1b3744e5 Use a consistent and more modern approach to not use a parameter. 
A remarkably creative and diverse set of approaches to letting the
compiler know that opaque was being used when it wasn't is changed
by this commit to the more standard (void)opaque.

Mark Adler 51a223def4 Avoid use of DEBUG macro -- change to ZLIB_DEBUG. 2015-07-28 22:44:31 -07:00
Mark Adler 62d6112a79 Clean up the usage of z_const and respect const usage within zlib. 
This patch allows zlib to compile cleanly with the -Wcast-qual gcc
warning enabled, but only if ZLIB_CONST is defined, which adds
const to next_in and msg in z_stream and in the in_func prototype.
A --const option is added to ./configure which adds -DZLIB_CONST
to the compile flags, and adds -Wcast-qual to the compile flags
when ZLIBGCCWARN is set in the environment.

Mark Adler 55b8b5fec1 Put gzflags() functionality back in zutil.c. 
gzflags() was put in gzwrite.c in order to be compiled exactly the
same as gzprintf(), so that it was guaranteed to return the correct
information.  However that causes a static linkage to zlib to bring
in many routines that are often not used.  All that is required to
duplicate the compilation environment of gzprintf() is to include
gzguts.h.  So that is now done in zutil.c to assure that the correct
flags are returned.

Mark Adler f442c1e89e Add a ./config --solo option to make zlib subset with no libary use 
A common request has been the ability to compile zlib to require no
other libraries.  This --solo option provides that ability.  The price
is that the gz*, compress*, and uncompress functions are eliminated,
and that the user must provide memory allocation and free routines to
deflate and inflate when initializing.

Mark Adler 00c836e325 Merge vestigial vsnprintf determination from zutil.h to gzguts.h. 
This also moves some of the same from zconf.h to gzguts.h. A new
function, gzflags(), was created to pass the compilation flags
related to vsnprintf usage back to zlibCompileFlags() in zutil.c.
In the process, various compiler configuration files were updated
to include gzflags(), as well as the new gzgetc_() function added
when the gzgetc() macro was introduced in a previous patch.
