No, at least not properly in all cases, because the parser knows which
keywords are type specifiers; __int64 seems to be designed as a keyword,
and implementing it as something else isn't a robust solution.  I don't
believe we want to add this extra keyword to GCC.  If the Intel compiler
makes __int64 a type compatible with long long and unsigned __int64
compatible with unsigned long long, or if it makes them compatible with
long / unsigned long (with 64-bit long), then just use the compatible
types.  If it is a type incompatible with all standard types of that size,
more consideration may be needed.
