gcc4 compilation error

[Jeff Sheltren]

Using gcc 4.0, I am unable to compile cfengine.  Here is what is output
during the build:

----------

if gcc -DHAVE_CONFIG_H -I. -I. -I. -I/usr/include/db4 -I/usr/include

----------

Apparently, the definition of OPTIONS[] in cf.extern.h is not allowed since
you can't have an array of incomplete types.  See
http://gcc.gnu.org/ml/gcc/2005-02/msg00053.html for a bit more info.  I am
not quite sure what to change to get this working correctly.
