* harbour/source/rtl/hbregex.c
* added hack to force linking newer PCRE versions not the one included
in BCC RTL when Harbour is compiled without HB_PCRE_REGEX_BCC.
If user application will uses regex expressions (directly or indirectly
by some RTL functions) then lining it without HBPCE should give link
time error that pcre_config() function is missing.
