I received no compiler warnings other than the reported problem with
size_t and NULL.  The console source file includes lib.h before it
includes Lua headers, so the other definitions must fit with Lua's
definitions.  The functions in lib.c take precedence over the ones in
the C library, so they better be good.  The definition of gettimeofday
also overrides that which is provided by the C library, which is good
because the C library simply provides a stub routine.  By the way, the
Lua allocator in the modified version of console.c does not free
enough.  I did that to look for malloc bugs, but forgot to remove the
change when it made no difference.
