> The files errors.c and errors.h define and declare some diagnostics

> toplev.h and diagnostic.c declare and define different diagnostics
> functions used by the rest of the compiler.

> found in errrors.h and toplev.h compatible. However, this has no
> future at all. They do not need to be compatible since they are not
> (or should not be) used in the same places. Moreover, being compatible
> has allowed errors.h to sneak into some compiler files where it does
> not belong. (I would prefer if errors.h and errors.c would rather be
> called generrors.h and generrors.c)

> This version should work in SPU, although I cannot test it so testing
