https://gcc.gnu.org/onlinedocs/gcc/Dollar-Signs.htmlThen a,b,d$ will be highlighted correctly as local vars, but not $ or
$e. The highlighting doesn't appear to work whenever $ is the first or
only character. Since emacs is accepting of the $ sign anywhere else in
the variable name, I suspect supporting $ was intended, even though it's
non-standard. Even if not intended, it's a popular syntax
extension supported by the major current compilers and whose history
goes back to the DEC compiler, so support would be nice.
