I'm not an expert on giza++ but a problem is that it creates similar files
that only differ in the case of the file name, eg
file.a3
file.A3
on operating systems that have case insensitive filesystems
(Windows/cygwin, Mac OSX) they cause problems as the files are overwritten.

I personally never use giza++, but instead use mgiza, directly from the
repository
http://sourceforge.net/projects/mgizapp/

If you have problem with mgiza, i might be able to help.

I personally think giza++ should be retired. There's no reason it should be
used anymore, given mgiza
