And no warnings as well ?
Weird, since this is the test that is used to dected long long presence
See m4/acinclude.m4

Do you run configure with CCFLAGS defined ? For example, if CCFLAGS="-Wall", then the test 
will throw a warning that will make it fail.
I'm not sure why we use CCFLAGS in that file, whereas CFLAGS is used everywhere else.

What if you change in m4/acinclude.m4
  echo 'int main() { long long off=0; }' >> conftest.c
to
  echo 'int main() { long long off=0; (void)off; return 0; }' > conftest.c

and run autoconf to regenerate configure ?
