Re^2: Slow Regex - How to Optimize

Notice that your code has a subtle bug.

Even if he is running the code through CPP first (to strip out comments, expand macros, rejoin lines), he still has plenty of corner cases to worry about (strings, fucntion pointers, etc)...

#define p printf

int mai\
n/*this is a comment: main()*/(int argc, char **argv)
{
    int (*f)(int, char **) = &main;

    p("hello world: main()\n");

    if(argc>0)
        f((argc-1),argv);
}

Oh, and don't forget that [^a-zA-Z] matches "(" and that C identifiers can have digits and underscores...

_foo2bar((4),2);
