// The Mixed Mode procInfos defined in npupp.h assume Think C-
// style calling conventions.  These conventions are used by
// Metrowerks with the exception of pointer return types, which
// in Metrowerks 68K are returned in A0, instead of the standard
// D0. Thus, since NPN_MemAlloc and NPN_UserAgent return pointers,
// Mixed Mode will return the values to a 68K plugin in D0, but 
// a 68K plugin compiled by Metrowerks will expect the result in
// A0.  The following pragma forces Metrowerks to use D0 instead.
