Yes, I agree that it is a great addition to GNU make, but...

The attached patch is more explicit (aka verbose) but it should keep the
compatibility with other make implementations.

It provides expected behaviour for "typical" make use cases (rm -f
textstyle/version.h && make textstyle/version.h do work as expected)
and explicitly named rules for the tasks involved. I've addressed the
order of the files, and the new rules ensure that the timestamps have
the exact order needed though.

The extra make calls could be an issue if they are performed often, but
actually are maintainer tasks with the exception of
prepare-libtextstyle-headers, that is performed after a mostly clean to
keep the object files and only recompile the ones including the header,
I guess.

What do you think?

Happy hacking,
Miguel
