Then make xxx_vprep.cxx depend on xxx.h and add it to _SOURCES (and
BUILT_SOURCES ?).

For GNU make, this is rather easy, but not if you want to remain
compatible with other makes, so I don't have any code handy.

The cleanest approach would be to add this into automake in some way
(similar to how yacc/flex support is now, i.e. you ship the _vprep file
with the sources in case the casual installer doesn't have your tool), but
I think this will be rather difficult.
