From Axel:

Try not to rely on ROOTSYS being set when building root. It's not needed
anyway (configure, root-config.in)

Use the NMAKE configuration also when cleaning (asimage, freetype)

Don't invoke a sub-shell for each ld - it's not needed (and converting
to windows path will make link com plain about a clash in dll names)

Allow python2.5 in configure (I tested python's CVS, it works - and it's
the only way to get python working with MSVC8).

Escape "\" also when writing config.status.
