I thought about that option at first time, but later I checked grep
ChangeLog and saw "pcre" USE flag was dropped time ago but later readded
due user request.

In my laptop, just now, only a few:
$ equery hasuse pcre
 * Searching for USE flag pcre ... 
[IP-] [  ] app-admin/syslog-ng-3.2.5:0
[IP-] [  ] dev-lang/swig-2.0.4-r1:0
[IP-] [  ] dev-libs/rasqal-0.9.28:0
[IP-] [  ] sys-apps/grep-2.9:0

but running it with "-p" shows me there are a lot that I don't know if
their support deserves to be enabled by default :(
