not libpcre, pcre (Perl-Compatible Regular Expressions) is used only
when you use grep -P (in recent evrsions of GNU grep).

When you use grep -G (default), or grep -E (egrep), the system regex
library is used.

Another variant would be to recompile grep with the regex lib from
current glibc, but it would present some work for you (not big).
Mail me/us if you are interested in details.

BTW, upcoming versions of gawk will probably use the regex library from
current glibc.
