Hi Rich,

I like to avoid in-function #ifdefs.
To that end, what do you think about a function like this:

    #ifdef HAVE_CFMAKERAW
    static void
    cfmakeraw (whatever)
    {
        rawattr.c_iflag &= ~(IGNBRK | BRKINT | PARMRK | ISTRIP
                             | INLCR | IGNCR | ICRNL | IXON);
        rawattr.c_oflag &= ~OPOST;
        rawattr.c_lflag &= ~(ECHO | ECHONL | ICANON | ISIG | IEXTEN);
        rawattr.c_cflag &= ~(CSIZE | PARENB);
        rawattr.c_cflag |= CS8;
    }
    #ifdef HAVE_CFMAKERAW

Then you don't have to change the code that *uses* cfmakeraw.
