I agree. That's why I put together posix.mak. On Windows things have 
remained that way because Walter doesn't want to depend on cygwin, so 
the make utility used on Windows is the one he wrote (which doesn't 
support many features of make).

If I had remote access to a Windows machine I'd be able to use posix.mak 
for the Windows build too. It used to work (on a machine donated by Adam 
Ruppe) but that machine has gone dark since.

The one odd thing to remember is that a rule's actions must start with a 
tab. That's about it.
