Subject: Add comile time information/settings from ./configure to --version
X-Git-Tag: v2.2-beta1~6^2~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f27bf509315a48b0070294c3993a718df0c2626c;p=thirdparty%2Fopenvpn.git

Add comile time information/settings from ./configure to --version

This patch will create ./configure.h which will contain two new #define
strings.  CONFIGURE_DEFINES will contain all USE, ENABLED, DISABLED and
DEPRECATED defines from ./config.h.  CONFIGURE_CALL will contain the
complete ./configure line which was used when configuring the package
for building.
