Hi Baptiste,
I cannot tell from this what you are really doing.

It would likely be best to keep the old history, so that would involve
a 'svn move usr.bin/lex contrib/flex'.

Additionally if flex is now considered to be 3rd-party code (signified by
living in contrib/) it should be imported we into '$REPO/base/vendor'.

These actions would give a different diff than that above.

Do you have a diff that shows what the real changes to FreeBSD are?

We don't seen to have '$REPO/base/vendor/OpenBSD/m4' as we likely should.
How different is our usr.bin/m4 from OpenBSD's?

I assume an import into '$REPO/base/vendor/gperf/' will happen first?
['$REPO/base/vendor/gperf/' needs to be "flattend out" first]

thanks,
