    Try taking out the "(unsigned int)" cast.  

That will fix the *symptom*, but it'll still be wrong since the proper
type to use can only be determined when the compiler runs since it
depends on the value of -m options: you can't determine it when the
compiler builds.

I noticed this a while ago and said that this is not easy to fix and
only somebody who knows g77 well can do it.
