It's only in CoinUtils so far.
I can put it also into Clp, but since configure does not know whether
UFL AMD is present, one would set -Wno-long-long always - shouldn't harm.

What other (undocumented) options for speeding up Clp by thirdparty
codes exists? I see there also ClpCholesky{Mumps,Taucs,Wssmp*}.?pp. Are
they all working?
