In cygwin, I found these macros in /usr/share/aclocal/pkg.m4. That
file is part of the pkg-config package.

So if I don't have pkg-config, then I don't have those macros, so they
can't be part of a test for whether I have pkg-config :(.

Neither the MinGW project (http://sourceforge.net/projects/mingw/) nor
the GnuWin32 project (http://sourceforge.net/projects/gnuwin32/) have
packages for pkg-config, so requiring pkg-config would not be simple.

This is the only occurrence of 'PKG_CONFIG' or 'pkg-config' in the
monotone sources. So perhaps this part of monotone configure should
simply ignore pkg-config, as the rest does?

Or we could include pkg.m4 in montone/m4. I've tested that solution;
it allows running 'configure' with MinGW, without
'--without-system-pcre', and the resulting pcre_config.h still has
PCRE_STATIC set to 1. And 'make' succeeds. So this is a workable
solution. 

Or these two macros could be expanded by hand in montone/m4/pcre.m4.
However, there is not much else in pkg.m4, so it would be much cleaner
to just include pkg.m4 in monotone/m4.

pkg-config is an excellent system for assisting in the configuration
of packages. It probably could be ported to MinGW, but we can't do
that before the 0.37 release.
