No -- and now I must offer my sincere and abject apologies.  There are two
definitions of volumelabel; one is a substantial function and the other is
very small.  I've given information from the big one:

#if (!defined(__GO32__) && !defined(__EMX__))

...

/**************************/
/* Function volumelabel() */
/**************************/

static int volumelabel(newlabel)
    char *newlabel;
...

(I'm still not sure how this is excluded from the DJGPP compile.)  There's
another routine within the function version(), and it looks like this:

...
#endif /* !__DJGPP__ || (__DJGPP__ < 2) */

static int volumelabel(char *name)
{
    int fd;
    return _dos_creat(name, FA_LABEL, &fd) ? fd : _dos_close(fd);
}
...

A printf inserted here shows up.

The fact that there are two functions is stated at the beginning of the
file, as shown below.  When I first searched for the alternate definition,
I searched for volumelabel() and only the first one showed up, which
puzzled me.  I was also puzzled by the __GO32__ condition for the
function, rather than the DJGPP condition I was expecting. I shouldn't
have let the matter go there, and I'm sorry for the confusion my
inattention has caused.
