* 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.

/* A problem turned up with PCRE_PRERELEASE, which is defined empty for

|
production releases. Originally, it was used naively in this code:

|
|
|
return XSTRING(PCRE_MAJOR)
|
|
"." XSTRING(PCRE_MINOR)
|
|
XSTRING(PCRE_PRERELEASE)
|
|
" " XSTRING(PCRE_DATE);
|
|
|
|
However, when PCRE_PRERELEASE is empty, this leads to an attempted expansion of
|
|
STRING(). The C standard states: "If (before argument substitution) any
|
|
argument consists of no preprocessing tokens, the behavior is undefined." It
|
|
turns out the gcc treats this case as a single empty string - which is what we
|
|
really want - but Visual C grumbles about the lack of an argument for the
|
|
macro. Unfortunately, both are within their rights. To cope with both ways of
|
|
handling this, I had resort to some messy hackery that does a test at run time.
|
|
I could find no way of detecting that a macro is defined as an empty string at
|
|
pre-processor time. This hack uses a standard trick for avoiding calling
|
|
the STRING macro with an empty argument when doing the test. */
