Dollars are not part of the standard character set for C, so it seems 
entirely reasonable to support it as an optional extension requiring a 
flag.  I don't know the details of tcc's standards support, but aiming 
for greater conformance by default is a good idea.

Note that on several processors, the standard assembly makes use of 
dollar signs for other purposes, such as referring to registers, local 
labels, or hexadecimal constants.  For such targets, having dollar signs 
in identifiers may complicate things, so it is not supported on all 
compilers.  And some linkers might not support it either.

The strange thing, as I see it, is for a code generator to make C code 
that has dollars in the identifiers.  The code generator could use 
whatever naming system it wants - it could mangle the identifiers so 
that the source code could use more "letters", or other features such as 
overloading, or encoding type information for extra error checking when 
linking multiple object files.  Clearly there are also advantages in 
keeping the identifier naming unchanged - it makes the generated C code 
easier to read, and will make it easier to use a debugger along with the 
C code.
