+ added hb_gcFunc(), hb_parptrGC(), hb_itemGetPtrGC()
hb_parptrGC() and hb_itemGetPtrGC() uses GC cleanup function address
to validate if pointer item points to expected memory block type

* formatting and minor modifications
* harbour/source/pp/pplib.c
* harbour/source/pp/pplib2.c
* use hb_parptrGC() to be sure that given pointer item points
to PP structure
+ harbour/include/hbregex.h
+ harbour/source/rtl/hbregex.c
* harbour/source/rtl/Makefile
* harbour/common.mak
+ added support for regular expressions. Now it's enabled by default
only in *nixes (POSIX regex) and BCC 5.5 (PCRE regex). Setting
HB_PCRE_REGEX macro enables Perl-Compatible Regular Expressions
and HB_POSIX_REGEX - POSIX regular expressions. In xHarbour regex
support is enabled for all builds because PCRE source code is stored
in CVS. If you will want we can make the same.
+ the following C functions are available:
hb_regexCompile(), hb_regexGet(), hb_regexFree(), hb_regexMatch()
+ the following PGR functions are available:
HB_REGEXCOMP(), HB_ISREGEX(), HB_ATX(), HB_REGEX(), HB_REGEXMATCH(),
HB_REGEXSPLIT(), HB_REGEXATX(), HB_REGEXALL()
They are working in similar way to the ones in xHarbour with the
exception to some bug fixes and form of compiled regular expression.
In Harbour it's pointer item for which HB_ISREGEX() returns TRUE when
in xHarbour it's binary string.

+ tests/ddate.prg
+ tests/switch.prg
+added support for DATE type constants in the following format:
0dYYYYMMDD
for example (see tests/ddate.prg for more):
IF( dDate > 0d20051112 )
+added support for SWITCH command (see tests/switch.prg)
SWITCH <expr>
CASE <integer_expression>
...
[EXIT]
CASE <string_expression>
...
[EXIT]
[OTHERWISE]
...
END
Notice:
- Integer and string expressions can be mixed in a single
SWITCH command with no runtime errors;
- CASE expression have to be resolved at compile time and
the result has to be either an integer or string constant
- if there is no EXIT statement then next CASE is executed
(or OTHERWISE for the last CASE)
For example:
CASE 1+32+2*4
CASE CHR(64)
CASE ASC('A')
CASE "A"+CHR(13)
Notice:
The above changes apply only to FLEX version!
