Get some newer apps...  ;-)

The app should not be attempting to prototype lseek().  Take a look and
see if it's conditional at all.

Basically the same here.
In both of these cases, the system declaration is _probably_ the correct
one and the offending local one should be deleted.  However, most packages
have some mechanism in place to fix this sort of thing--defines in some
header file(s), Makefile(s), etc.
