Yes, pcreposix.h is also there.

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

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

Yep.  Presumably this needs some autoconf wizardry to set
HAVE_PCRE_PCRE_H in the first place, which is where I get lost ...

Just add it to AC_CHECK_HEADERS(...), near pcre.h.

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

There must be a bug in that too then, because I get

  checking for pcre.h... no

There is probably no bug. I meant "we should add code to pcre.mdd to conditionally compile it", not that it is already there. Currently it is unconditional.

Ideally, it would be nice to have some high level means to specify conditions ... probably something like


or like. It is better to no add any autoconf-dependent code to mdd files.
