yeah, I'm working on the version from the dev-tools/make-3.82-gbuild 
repository

It's detecting gcc and compiling a normal version fine, but it's not 
compiling the stuff behind the WINDOWS32 #define
Maybe I should be using a different #define, something like
#ifdef WINDOWS32 || __CYGWIN__

I've coded 2 variants, one general purpose and one specific to windows.
Because
(a) on Windows, I can implement "touch" using exactly one system call,
(b) and because it's practice for some of the other optimisations I'd 
like to do :-)

True, which is why I coded the general purpose variant (largely borrowed 
from GNU touch)
