valac does not currently support any transformation on the output names
of the .c files. It's not as easy as a simple -o option because you have
multiple input and output files per invocation in general (see below).
If you think it would make sense to add a --suffix option or similar to
valac, I could certainly take a look at it.

That was not intentional. valac won't mind unnecessary .c files but will
reject files with other extensions.

This would be the correct commandline.

This would not work, valac requires all Vala source files of the same
program / library on the same commandline. The reason is that the source
files can depend on each other, but there is no header/include
mechanism.

We'd probably need to add a new commandline option to valac as suggested
in the first paragraph.
Thanks,
