i am not sure about the C identifiers, but they are widely used in the debug
info symbols, generated by SDCC.
i kindly ask not to break that debug info functionality.
probably in the identifiers that are visible from C they are not needed.
also $ symbol is used in the inline assembly (reusable labels), so in the
inline asm in __asm / __endasm form
they are very common.
For now, I was only wondering about the use of $ in C identifiers. What
is allowed int he assembler is a different story (though IMO the
identifiers allowed in C should be a subset of those allowed in the
assembler for straightforward implementation).
