IMO, this is similar to the reservation of _Z to the C++ ABI.  The C
compiler doesn't enforce that and shouldn't.  I think we should allow
dollars-in-identifiers except on targets where it is known not to work.


I don't mind either way, provided this doesn't affect the ABI exported
by any libraries built with the compiler.

FWIW, I agree with Daniel and Joseph that allowing this is OK, and with Richard that we should not have dollar signs appearing in the generated code unless explicitly present in the user's input. Given Richard's acquiescence, Joseph, I think you can go ahead with the patch.

Thanks,
