Great.

This version was suggested bu Elie Roux.

If [ -x `which svnversion` ] evaluates to true where there is no
subversion, I think that counts as a bug in mingw that maybe you
should file a bug report about.

But this doesn't look bad either. Elie, is this ok? (my shell
script skills are not that high either).

Perhaps the call to getluatexsvnversion.sh should be an explicit
option for build.sh instead of implied, but I prefer the rev. number
to reflect the actual state of the repository, so I would like to
leave the svn up command in it.

Probably. As I wrote above, I am not that good in shell either,
and the generated header is not in the repository so I don't think
it matters a whole lot, but if someone writes a patch I will apply it.
