The smoking gun on broken hardware is if the internal compiler error
moves around to other source files.

That line in utils.c is pretty simple. I don't see much of a problem with it.

Since MythTV has almost a complete set of libraries, you could try installing
a different compiler. A 4.2 vintage is probably fine.

I have Kubuntu 8.10 installed with roughly the same version compiler that
ships with Fedora 10. Although it flags all sorts of new warnings, it does
compile up just fine.

There was a semi-recent thread on this list about compiler errors. You might
want to look it over and see if it provides any insight.
