* Changed the way embedded zlib and pcre are handled:
- They now reside in /external dir.
- They are now excluded from Harbour dynlib. This means they
will now be linked statically on non-*nix systems and
dynamically on *nix systems. On *nix it's probably easy to
switch to link statically. On non-*nix this is quite
complicated to do.
- If these libs are provided by the system, those will be used.
- On non-*nix systems the locally hosted versions will be used,
unless user overrides them using HB_INC_PCRE or HB_INC_ZLIB.
- There is currently no officially supported way to force usage
of locally hosted libs.
- If PCRE lib is forcibly disabled or not found, build system
will fall back to POSIX regex on *nix systems and Borland regex
with bcc compiler. Otherwise it will stop the build with an error.
- If zlib is forcibly disabled or not found, an error will be
generated at build-time (in hbrtl). hbmzip is simply skipped
in this case.
- hbmk2 will use local builds of these libs if they are present
in lib dir.
; TOFIX: hbmk script.
; TOFIX: dos builds. cmdline lenghts are most probably too big for them.
; NOTE: Bumps are expected.
; NOTE: I've yet to test/verify it.

/* ===========================================================================
|
|
Decompresses the source buffer into the destination buffer. sourceLen is
|
|
the byte length of the source buffer. Upon entry, destLen is the total
|
|
size of the destination buffer, which must be large enough to hold the
|
|
entire uncompressed data. (The size of the uncompressed data must have
|
|
been saved previously by the compressor and transmitted to the decompressor
|
|
by some mechanism outside the scope of this compression library.)
|
|
Upon exit, destLen is the actual size of the compressed buffer.
|
|
This function can be used to decompress a whole file at once if the
|
|
input file is mmap'ed.
|
|
|
|
uncompress returns Z_OK if success, Z_MEM_ERROR if there was not
|
|
enough memory, Z_BUF_ERROR if there was not enough room in the output
|
|
buffer, or Z_DATA_ERROR if the input data was corrupted.
