This is from zlib header:

The data format used by the zlib library is described by RFCs (Request for
Comments) 1950 to 1952 in the files http://www.ietf.org/rfc/rfc1950.txt
(zlib format), rfc1951.txt (deflate format) and rfc1952.txt (gzip format).

so as you can see it can be added to Harbour core code without any
problems. I think that separate directory like source/hbpcre will
be good place for it and just like for PCRE we should add easy to
use option for people who will want use platform native zlib
implementation. For PCRE we have set of macros you can set in C_USR
envvar before building Harbour to reach such effect, f.e. -DHB_POSIX_REGEX
We can use:
HB_POSIX_REGEX - use POSIX regex instead of PCRE, it should work
on all POSIX systems (f.e. in *nixes)
HB_PCRE_REGEX - use platform native PCRE library
HB_PCRE_REGEX_BCC - use old PCRE library build into BCC CRTL
when non of the above is set then our own copy of PCRE is used.
best regards,
Przemek
