Mark Adler f7d01aae6e Avoid out-of-bounds pointer arithmetic in inflateCopy(). 
Though it does not matter for code correctness, clang's UBSan
injects code that complains about computing a pointer from an array
where the result is out-of-bounds for that array, even though the
pointer is never dereferenced. Go figure. This commit avoids that
possibility when computing distcode in inflateCopy().

that has just been compressed with deflate.

Ram Shanker 534864bccd Add build folder to .gitignore. 
A library is usually expected to be built in a folder /build at
its root. Whenever this repository is added as a submodule of
another project and compiled, git shows all the generated files as
changes. To suppress those git messages, this ignores the build
folder.

Mark Adler 7e6f0784cc Remedy conflict between libzip and minizip zip.h. 
minizip.pc.in would add @include@/minizip to the include path,
which would permit simply #include <zip.h> to use minizip. However
that conflicts with the zip.h from libzip that is put in the root
include directory. This now does not add /minizip to the include
path. Now when using pkg-config, #include <minizip/zip.h> must be
used, where #include <zip.h> would be used for libzip. This is an
incompatible change with the previous state. Users of minizip and
pkg-config will need to update their code. #include <unzip.h> will
need to be updated to #include <minizip/unzip.h> as well.

Alexander Miller f02ea29e5f Improve detection of UNIX-style systems in minizip. 
Not all toolchains on UNIX-style operating systems predefine
"unix". For example, it's missing on NetBSD, OpenBSD/gcc, AIX,
HP-UX. There is no single macro defined everywhere, but checking
both "__unix__" and "__unix" should cover everything except macOS,
which is already checked for using "__APPLE__".

Note that case sensitivity should default to off on macOS and
cygwin, so the check there is different.

Mark Adler e342bb3dae Assume no snprintf() or vsnprintf() if C89/90 in gzguts.h. 
Those functions were introduced in C99. However it is assumed that
they are there if under Windows, since Visual C claims C89/90, but
does have those functions, or variants.

Mark Adler 915a3d5b7b Avoid use of snprintf() in test/minigzip.c. 
It was being used only as a safe version of strcpy(). Instead, use
a safe alternative to strcpy().
