[rdiff-backup-users] Rdiff-backup hangs on Cygwin, if source or target directory is on a FAT32 FS

[Ralph Lehmann]

Hi,

I've compiled the current version from cvs, and it works fine with NTFS.
Unfortunately rdiff-backup hangs, if it should read from or write to a
FAT32 Filesystem in a Cygwin environment.

Note, that this problem do _not_ occur, if I try to read from or write
to FAT32 on OSX (Intel).

Thats all.

It seems to me, that hard linking could be the problem, cause this is
not supported on FAT32.
