Do they have anything else in /usr/include/pcre? Else I'd call this broken
(yet another thing in 7.0).


Obvious fix is to check for both pcre.h and pcre/pcre.h and take whatever
exists

#ifdef HAVE_PCRE_H
#include <pcre.h>
#else
#ifdef HAVE_PCRE_PCRE_H - ick!
#include <pcre/pcre.h>
#else
#error pcre not found
#endif
#endif

Additionally, pcre should be compiled conditionally only if prerequisites
are found (compare termcap.mdd or terminfo.mdd).
