[Omake] Adding version control/time stamp info to the module

[Dmitry Bely]

Aleksey,

Thank you very much for you Subversion recipe, but one thing is still
unclear for me. You wrote:

In the simplest case if I have something like

files = ...
program = ...
.DEFAULT: $(OcamlProgram(program, files))

How to make version.h depend on on "all the source files"? Should I
duplicate all OcamlProgram() logic with

CMOFILES  = $(addsuffix .cmo, $(files))
CMXFILES  = $(addsuffix .cmx, $(files))
...
version.h.byte: $(CMOFILES) ...
...
version.h.opt: $(CMXFILES) ...
...

if $(NATIVE_ENABLED)
     version.h: version.h.opt
         ln-or-cp $< $@
else
     version.h: version.h.byte
         ln-or-cp $< $@

or there is a simpler way?
