m1 failed, but i have no idea  if we should fix it in tcc, it's not that important

Okay, I see.  We need to force a space.

do we have better way?

Don't know.  Now it's up to you to choose ;)

another example:

#define CONC(a,b) a/**/b


to fix it, return ' ' when see a /**/comment(also c++ comment?) in  next_nomacro1 which

       /* comments or operator */
   case '/':
       PEEKC(c, p);
       if (c == '*') {
           p = parse_comment(p);
#if 1
       tok = ' ';
       goto keep_tok_flags;
#endif
           goto redo_no_start;

Yes, why not.

While at it please put declaration above statements to stay
c89 compatible.  Not everybody here uses gcc to compile tcc:

   macro_str1 = macro_twosharps(ptr);
   int append_space = 0;

Thanks,
