Yes, and because of that, build on Win32-ish was failing; but also you need 
to have configure check for bcopy(), because bcopy() isn't there on Win32-
Gnu-ish platforms (I have been told it is part of GlibC, but Cygwin, etc 
are based on Newlib, not GlibC).

A part of <make.h> needs to be rewritten because it appears that at some 
point an ad-hoc (?) addition was made to try to deal with lack of bcopy(), 
but was done not properly, by getting into configure and making the needed 
changes there. Sorry i don't have the sources unpacked where I am right 
now, so i cannot cite a line number. Unpacking and viewing the diff at the 
url (below) would yield the approximate location of the part I am talking 
about (approximate because the diff is against patched rc1 source, not 
current CVS source).

My sitelet at
 http://home.att.net/~perlspinr/build_platforms/mingw-make/#c_i
tries to document this problem.
