Bug description:  realpath doesn't canonicalize drive letter case

Description:
------------
The realpath function doesn't canonicalize the case of the drive letter on
Windows (and possibly on certain other platforms).

For example:
realpath('C:\WINDOWS') returns 'C:\WINDOWS'
but realpath('c:\WINDOWS') returns 'c:\WINDOWS'
(note the different case of the 'C:')

Hence comparing realpaths cannot reliably be used to check that two files
are the same on Windows.

Reproduce code:
---------------
echo (realpath('C:\WINDOWS')==realpath('c:\WINDOWS')) ? "true" :
"false";

Expected result:
----------------
true

Actual result:
--------------
false
