# The perl extension build mechanism works by generating a Makefile from a
# template Makefile.PL file in the extension directory. Unfortunately this
# generated Makefile has a dependency against both the original Makefile.PL as
# well as config.sh and config.h. If triggered, the rule for this dependency
# rebuilds the Makefile from Makefile.PL and exits the make by calling 'false'.
# This behaviour is unacceptable in the context of ON, where the build must
# succeed wherever possible. This script generates a makefile that mimics
# that generated by the Makefile.PL, so that we can ensure that the extension
# make will always pass the relevant dependency checks, and will build
# sucessfully. The output of this script is a combination of parts of make_ext
# and the dependencies from the various module Makefiles. Note also that the
# generated rules unset VERSION in the environment before calling make, to avoid
# a clash between the Solaris and Perl uses of this variable.
