Then you'll have to submit a bug report with a sample program that
demonstrates the program, otherwise we cannot fix it.

It has nothing to do with whose word counts; the compiler simply can
only contain one code generator. The fpc wrapper can however call
different compilers based on the -P switch (-P386 -> call ppc386, -
Px86_64 -> call ppx64, ...).

That's an error in the way the rpms are built then, but I don't know
nothing about rpm building. The default configurations support
multiple concurrently installed versions (for the same or different
architectures) out of the box.
