case-sensitiveness of environment problem

[egor duda]

Hi!

  if cygwin environment contains both 'Path' and 'PATH', creating
windows environment from it causes crash due to reallocating memory
object which is externally referenced. this patch fixes that.

i feel that we need a bit more tweaking with environment to deal with
it case-insensitiveness under win32.
