Gcc3.4.1 finds probable bug

[Andrew Walrond]

As well as the log2 problem already mentioned, compiling with gcc3.4.1
fails with a warning in libparted/disk_dos.c, and finds what I believe
to be a bug. See first part of patch below. The second bit addresses the log2
problem already mentioned.

Hope this is useful
