In the "old days" before automake and CMake, pcredemo was not built with
PCRE. I provided it as a demonstration program for people to build
themselves, as users of PCRE. When it was included in the automake
build, I didn't object (other things to worry about, life's too short,
etc, etc). Needless to say, it builds OK on Linux.

Looks like it couldn't find any of the PCRE functions, but why that
should be, I don't know. Hmm... there is a difference in the way they
are defined in the automake input:
bin_PROGRAMS += pcregrep
pcregrep_SOURCES = pcregrep.c
pcregrep_LDADD = libpcreposix.la
noinst_PROGRAMS += pcredemo
pcredemo_SOURCES = pcredemo.c
pcredemo_LDADD = libpcre.la
Notice the different libraries. I wonder if that makes a difference?
Neither of them actually uses the POSIX functions.
