Changes between 0.9.6 and 0.9.6a [xx XXX 2001]
+ *) Change bctest to avoid here-documents inside command substitution
+ (workaround for FreeBSD /bin/sh bug).
+ [Bodo Moeller]
+
*) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
with des_encrypt() defined on some operating systems, like Solaris
and UnixWare.
(but broken) behaviour.
[Steve Henson]
+ *) Enhance bctest to search for a working bc along $PATH and print
+ it when found.
+ [Tim Rice <tim@multitalents.net> via Richard Levitte]
+
*) Fix memory leaks in err.c: free err_data string if necessary;
don't write to the wrong index in ERR_set_error_data.
[Bodo Moeller]
