Building starttls on Red Hat

Wanderlust has the ability to send mail using STARTTLS, but requires some help to make it all happen. Building the small C program included on Red Hat Enterprise Linux 3 (RHEL3 from now on!) required more effort than on my older Debian systems. The OpenSSL bits included in RHEL3 require that Kerberos header files are installed, which they don't seem to be for me.

Easily fixed, given that the header files already allow for the situation. Unpack starttls and then use a modified configuration process:

CC="gcc -DOPENSSL_NO_KRB5" ./configure

Everything works just fine.
