Matthias,
Okay, I just put a bunch of stuff in the CVS:
(1) your earlier patch (pre-variable argument macro fix)
(2) some warning removals
(3) my own vararg stuff (we'll have to reconcile our versions)
(4) removed generated files from CVS
(5) fixed --disable-crypto
(6) a better undefined TUNNEWPPA error for Solaris
Still to do:
(1) _* name renaming
(2) merge your warnings quencher #1
(3) the removal of install-sh seems to have broken rpmbuild -tb [tarball]
(4) reconcile macro vararg approaches
Question: What's the best way to generate a tarball that has ./configure
already generated, so that openvpn can be built and installed with the
usual "./configure && make && make install"?
