Given that they will ship the version without special instructions for compatibility, most systems will not be affected by such optimizations.

An explicit global library initialization function might also do. regards, Nikos _______________________________________________ nettle-bugs mailing list [email protected] http://lists.lysator.liu.se/mailman/listinfo/nettle-bugs
