AC_OPENMP, default off

[Bob Friesenhahn]

It seems that AC_OPENMP always defaults to enabled by default.  This 
causes problems for packages that would prefer that this feature be 
disabled by default.  OpenMP is pretty invasive since it adds 
additional library dependencies.

Is there a way to use AC_OPENMP in a default disabled state without 
creating a modified version of the macro and without adding another 
option to the configure script?

Thanks,

Bob
