[rdiff-backup-users] fails on powerpc with some files

[David Bélanger]

Hi,

I tried to register twice on librsync list but it didn't want to accept my
confirmation...

Anyway, I was having a lot of UpdateErrors with rdiff-backup on
Gentoo Linux/powerpc.  On x86, works great.  Simply touching the
file (i.e. changing its timestamps) can lead to these errors.

When I added a fprintf to help debugging, I found that the addition
of the fprintf "solves" magically the problem.

I relaxed the optimization and even try with -O0 but I never
got it able to work.  I tried with both gcc 3.3.3 and 3.4.  I will
probably install gcc 2.95 to try out...

Any clue?
