This seems weird. Both fseeko and ftello use the type 'off_t' in their
prototypes. If the compiler did not complain when reading the header
files, either their prototypes are missing from 'stdio.h' (where these
functions should be declared) or their prototypes are not using this
type. Both cases seem to break POSIX compliance.
