[Exim] tls problems in exim-4.30

I have a curious problem with exim-4.30 on an Alpha
running Tru64 V5.1B. Apart from the build-error below
(which is fixed by adding the line:

typedef int socklen_t;

to exim.h)

=========================================================================
cc -c -O -I.   -I/usr/local/ssl/include/openssl/ daemon.c
cc: Error: daemon.c, line 144: In this declaration, "socklen_t" must specify a type. (badparsedecl)
socklen_t ifsize = sizeof(interface_sockaddr);

I also get a configfile error at startup. The program is built with
the appropriate TLS options enabled, but when it starts, it complains
about tls_option lines:

and yet still offers STARTTLS at the SMTP EHLO command:

TLS section of Makefile
-----------------------
#------------------------------------------------------------------------------
# Exim can be built to support the SMTP STARTTLS command, which implements
# Transport Layer Security using SSL (Secure Sockets Layer). To do this, you
# must install the OpenSSL library package or the GnuTLS library. Exim contains
# no cryptographic code of its own. Uncomment the following lines if you want
# to build Exim with TLS support. If you don't know what this is all about,
# leave these settings commented out.

# This setting is required for any TLS support (either OpenSSL or GnuTLS)
SUPPORT_TLS=yes

# Uncomment this setting if you are using OpenSSL
TLS_LIBS=-lssl -lcrypto

# Uncomment these settings if you are using GnuTLS
# USE_GNUTLS=yes
# TLS_LIBS=-lgnutls -ltasn1 -lgcrypt

# If you are running Exim as a server, note that just building it with TLS
# support is not all you need to do. You also need to set up a suitable
# certificate, and tell Exim about it by means of the tls_certificate
# and tls_privatekey run time options. You also need to set tls_advertise_hosts
# to specify the hosts to which Exim advertises TLS support. On the other hand,
# if you are running Exim only as a client, building it with TLS support
# is all you need to do.

# Additional libraries and include files are required for both OpenSSL and
# GnuTLS. The TLS_LIBS settings above assume that the libraries are installed
# with all your other libraries. If they are in a special directory, you may
# need something like

# TLS_LIBS=-L/usr/local/openssl/lib -lssl -lcrypto
TLS_LIBS=-L/usr/local/ssl/lib -lssl -lcrypto
# or
# TLS_LIBS=-L/opt/gnu/lib -lgnutls -ltasn1 -lgcrypt

# TLS_LIBS is included only on the command for linking Exim itself, not on any
# auxiliary programs. If the include files are not in a standard place, you can
# set TLS_INCLUDE to specify where they are, for example:

TLS_INCLUDE=-I/usr/local/ssl/include/openssl/
# TLS_INCLUDE=-I/usr/local/openssl/include/
# or
# TLS_INCLUDE=-I/opt/gnu/include

# You don't need to set TLS_INCLUDE if the relevant directories are already
# specified in INCLUDE.

Its bound to be something ridiculously simple, but I cant see it.
Please put me out of my misery.

Thanks,
Terry.
