Nope, PCRE should behave consistently across platforms if the same 
version is installed on those platforms (although I'd be somewhat unsure 
about its handling of line ending conventions and unicode/different 
character sets on different platforms.)
But I was responding to "platform's support library" which might be 
anything from PCRE through some POSIX compatible regex (from the GNU C 
library or some other implementation) to anything else that might be 
there (see http://unixpapa.com/incnote/regex.html for a list of 
possibilities).
