-Wimplicit-function-declaration has been turned on by default in
configure for more than a year.  On GNU/Linux (and probably most other
platforms that use configure+gcc)  -Wimplicit-function-declaration does
not produce any warnings.  Fixing all these warnings on windows too would be
a good idea...
