it will be tested by anybody using git svn clone, right ?

yeah, sorry about that, I wasn't aware there were windows-specific
Makefiles with duplicated logic in the repository.

Fair enough. But don't you think it's a bit odd to couple the repository
compilation with the availability of a specific SCM tool ?

I mean, R just won't build unless you have svn info available, I think
that's pretty odd. Printing a warning would be another possibility, but
exitting build is almost an overreaction.

But fair enough, no need to spend days discussing $subject if the
community doesn't want to support git svn clone ;-)

cheers
