Below is a patch for ExtUtils::MakeMaker.pm (against v5.45) that will
print out any parameters returned from a 'CONFIGURE' directive in the
'Makefile' that is generated.  I found this useful when using the
'CONFIGURE' directive in a Makefile.PL for Bugzilla (still working on
it).

Hope you find it useful!
