no, configure.in has not changed, but your compiler has :-) Seriously, 
gcc4 now warns about these things whereas gcc3.x didn't say a word about 
it. You can get rid of this particular warning by adding 
-Wno-pointer-sign to the environment variable CFLAGS before you start 
configure.

This particular warnings tends to show up a *lot* in old C code. I'm 
actually not quite sure whether the warning is really that important.
