The new test skeleton should be compatible with compilation in C90 mode. I expect to use some of these helper functions for future build support on the host (that is, these routines will have to be compiled twice, once against the built libc, and once against the host libc). I converted a few tests to make sure that this works as expected. I do not propose bulk migration at this point. Some obscure use cases are not supported by the exported hooks. If you think this goes in the right direction, I will port over my container-based nss_files testing, and the resolver test suite to this infrastructure. It also eliminates the need for the hack in my fix for bug 16421 I posted earlier. Tested on aarch64, ppc64le, s390x, x86_64. Thanks, Florian extras: Introduce new subdirectory for test infrastructure 2016-11-25 Florian Weimer New subdirectory extras for build and test infrastructure. * Makeconfig (link-extra-libs-tests): Define.
