    dollar sign is legal in gcc

    hi,

    consider this:

    #include <iostream.h>

    int main()
    {
    int $one;

    cout << $one;
    return 0;
    }

    i've tried this code on bcc 5.5 and it does not compile, but on gcc 2.95 (on linux) it compiles perfectly. why?

    GG is correct. The '$' character may not be part of an identifier under ANSI C. You can force gcc to adhere strictly to ANSI C by using the -ansi switch in your compiles. What you lose with the -ansi switch are the keywords asm, inline, and typeof (as well as some macros). The gcc man page has all the details.
