Steffen Mueller actually has all of ext/util/make_ext re-written in Perl,
but (I believe) doesn't have ext/util_make_ext_cross integrated with it,
nor has anyone dealt with the make clean; make distclean problem described.
(make distclean; on its own works fine)

Also, Yves thought it easier to convert ext/util/make_ext to Perl first, then
figure out how to merge it with the Win32 code, rather than trying to compare
a shell script with Perl code.

So best to work out how to avoid duplicating work.

As far as he and I can see, make_ext_cross is identical to make_ext, except
that it invokes Makefile.PL with -MCross. So I assume that the right way
forward is to add an option to the new to use -MCross, and then
change the 4 lines in Cross/Makefile-cross-SH that currently invoke
make_ext_cross, to instead invoke with the 'use -MCross' option

So is it best if we patch blead to change ext/util/make_ext to
ext/util/, and then let you patch that (and test it) to incorporate
the -MCross option, and eliminate ext/util/make_ext_cross ?

(then sort out disclean, and work out how to merge the Win32 code)
