// Ippl and gmsg should only be built once, in globals.cc.o
//
// We declare them as extern for all other code to be consistent with usage in 
// C++ Opal; but we define them if we are including from Globals.cc so that the 
// extern is satisfied.
//
// Maybe this implements one gmsg per python module - which is wrong? So maybe
// some more linker/cmake dark arts required here? Do they have much global 
// state?
