They are *not* defined by default.  Unless the compiler is invoked
with -ansi or -posix, or the sources define _POSIX_SOURCE (which they
shouldn't), these definitions are always visible.

Did you resurrect the "struct" in "struct timeval"?  If not, this is
your problem.

If that doesn't help, you will have to dig deeper into this.  I'm
guessing that the compiler doesn't see <time.h> due to some #ifdef or
another cpp trick.

If you cannot figure this out, try to throw together the shortest
source which #include's only standard headers and exhibits the error
message, and post it here together with the compilation command line
you are using.
