Unfortunately this broke something more important:

#include <string.h>
#include <stdio.h>

int
main ()
{
  int rc = strverscmp ("2.6.21", "2.6.20");
  printf ("2.6.21 %s 2.6.20\n", (rc < 0 ? "<" : rc == 0 ? "=" : ">"));
  rc = strverscmp ("2.6.20", "2.6.21");
  printf ("2.6.20 %s 2.6.21\n", (rc < 0 ? "<" : rc == 0 ? "=" : ">"));
}

now prints:
2.6.21 < 2.6.20
2.6.20 < 2.6.21
while it used to correctly print:
2.6.21 > 2.6.20
2.6.20 < 2.6.21

Seems it wasn't the change in proposed in the original comment, but the
follow-up cleanups.
