 Oh, right.  We could now do the "mask to correct size" trick; I don't
 have any better ideas short of a real arbitrary-precision library
 (which we need eventually but I'm not going there just now).

 I believe we ought to be able to do most of it by adding entries to
 the options structure, which are set by cc1 during initialization.
 GDB needn't bother initializing them, since it only needs the macro
 expander, and it will have the target-dependent macro values right
 there in the debug information.
