I notice many differences between the default config for two versions
above. Of these, I suspect "--with-float=soft" missing in the
configuration for gcc4.5.1 could be behind those errors.

Can you try explicitly enabling this option (if not already) to
compiler options when building with gcc4.5.1?

I am far from my build machine to check default barebox flags :(
