NO_DOLLAR_IN_LABEL means that the assembler can't accept $ in a
label.  If the C++ compiler ignores this then I imagine it will simply
fail to work on such platforms.

Here's what tm.texi says:

    @findex NO_DOLLAR_IN_LABEL
    Define this macro if the assembler does not accept the character
    @samp{$} in label names.  By default constructors and destructors in
    G++ have @samp{$} in the identifiers.  If this macro is defined,
    @samp{.} is used instead.

This is unfortunate since using `.' instead probably isn't what we
want.  But perhaps the final sentence here is simply out of date.

I think updating the C++ compiler is the right approach.
