This is correct.  configure is just a tool to help solve portability
problems.  The programmer must still provide the solutions.

All the checking in the world does no good if you just ignore the

Likewise, configure itself is useless unless you actually check for
the problems your code encounters.  Eg you can blindly use getcwd() if
you want, but then your code will just not compile on machines with
getwd() and not getcwd().  You can hardly blame configure for this --
the same problem would hold for any configuration system.
