But you'll probably agree that in 99.99 % of all cases, strtol() is
used using a fixed, developer-given value for base. ;-)

Btw., first checking for a valid conversion (using endptr), and then
checking errno would still work fine in that case, as after the
conversion was identified to be valid, the only source for errno ==
EINVAL remaining is a wrong value for `base'.  So there's still no
need to explicitly consider EINVAL in any other context...

But I guess we are really starting to bore anyone else, so if you
still disagree with the above, let's take that privately, poshalujsta.
