Which phase was the first compile error encountered in? The dependency
file generation phase, or the real make phase?

Does it continue with errors in the real make phase?

Since gmake builds ahead all the included dependency files as goals,
in your case (assumed), it compiles your C files as the generation of
dependency files. And perhaps that why you don't see the errors stop.

Better to seperate the dependency generation from the real compilation.
