It seems a little silly to implement a configure flag in configure.in to define ENABLE_SSL , only for dpi/https.c to ignore it! This patch: * changes --disable-ssl to --enable-ssl * changes dpi/https.c to respect --enable-ssl The default is to disable SSL. The configure script will issue a stern warning about alpha code if --enable-ssl is used. The DPI warning when SSL is disabled has been changed to explain about --enable-ssl . Regards, Jeremy Henty
