The first compilation test to get baseline warnings was getting more messages due to a missing object.d file, compared to later configure tests where libphobos is in the include paths. Because there must always be an object module during compilation, let the tests themselves be an empty object module instead. libphobos/ChangeLog: 2019-04-24 Iain Buclaw <ibuclaw@gdcproject.org> PR d/88431 * configure: Regenerate. * m4/libtool.m4 (lt_simple_compile_test_code): Update to not have dependencies on libphobos. (lt_simple_link_test_code): Likewise. (GDCFLAGS): Don't override for D compiler tests. From-SVN: r270531
