I suspect that any other packages that use unsigned long long
arithmetic would have the same problem, but those might not be that
common.

Even compiling Damien's test program and linking by hand exhibits the
same problem:

$ gcc -c testprog.c
$ ld -o testprog testprog.o -lc
ld: warning: cannot find entry symbol _start; defaulting to
00000000000101c8
testprog.o: In function `main':
testprog.c:(.text+0x24): undefined reference to `__udivdi3'

I think that it's going to be dependent on the system and compiler
config.  As a general rule, configure assumes that if you set things
like LD then you had a reason for it.
