Paul,

Thanks for your reply. 

Yes the V3.16rc2 does compile without issues on SLX 14.1 X64.

The other workaround also worked. 

Many thanks.

Can you try

http://download.libreswan.org/development/libreswan-3.16rc2.tar.gz

and let us know if that resolves your problem? We did some tweaks to support various older/newer combinations of flex/bison recently.

A quick workaround is to use: export WERROR_CFLAGS=''

We turned all warnings into errors :)
