Probably because allowing '$' in identifiers is a non-standard
extension, and the authors of tcc initially chose not to enable it by
default.

Different C compilers support different dialects when invoked with no
additional options, chosen at the whim of the compiler developers.  If
you want a compiler that conforms to (a specified edition of) the
standard *or* if you want to support '$' in identifiers, you have to
find out how to do that for each compiler you're using.  There's no
requirement for any compiler to support any such extensions at all.

But you know all that.

Incidentally, tcc on my Ubuntu system does allow '$' in identifiers by
default.  It was enabled by default in release 0.9.27; 0.9.26 didn't
have the option.  You must be using some intermediate version.
