Python 2.3.3 seems to be able to do it on Red Hat Linux 9.0:

[rodh at rodh rodh]$ python
Python 2.3.3 (#1, Dec 20 2003, 17:47:13)
[GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> '%.64f' % 0.1
'0.1000000000000000055511151231257827021181583404541015625000000000'
 >>>


Must be a M$ MSC problem.
