Tom,

I tried the int8 type onder BSD/OS, running 6.3.2 (contrib/int8). There the
%Ld type is unimplemented and %lld or %qd both work.

For BSD/OS 3.1, since DLSUFFIX is .o (static shared libraries), there is a
circular dependence in the Makefile. This is resolved by commenting out (or
ifdefing) the following segment:

int8$(DLSUFFIX): int8.o
$(CC) -shared -o int8$(DLSUFFIX) int8.o $(CLIBS)

Under BSD/OS 4.0 this should not be neccesary, as it supports Linux style
shared libraries.

I am missing the aggregate functions, such as sum() to deal with int8. Perhaps
these could be easily added? Is there problem to add all functionality that
exists for int4 to the int8 type?
