In this particular case, I suspect that Axiom will be best built under
Cygwin or variants where Unix convertion is quite dominant (I know you
can use the Windows style, but very often they cause troubles).  And
it is just easy to fix the environment.  In this particular case.  I'm
not saying Axiom should not support them.  I'm saying it really has
low priority on lis of things to do.  From experience, I know that for
GCC we had people trying to build GCC with embedded colons.  That was
a pain in the ass and usually led to obscure codes.  
My personal opinion is that the codes should not be obscured just to
support exotic stuff.  YMMV.

I suspect a good part of it is in  The rest
keeps poping when I try different ideas in different local trees.
I'll upate  Some of them are not really
related to build machinery.
