You also want a url in there to make subversion revision a unique identifier.
For in-tree build, you can have Makefile generate a header from
grep -e revision= -e url= $^ | head 2> $@
in the makefile should be sufficient.
For an out of tree build, you just stick something into version.h.
after you do svn export.
Its also important to have a default version identifier by
keeping a backup version.h under include directory, have that
picked up after the local version if that doesnt exist.
