On my setup with glibc-2.8, benchmark_residual linkage fails with undefines references to clock_gettime(). Adding -lrt fixes that. The following is a small patch for it.

(OTOH, GCC 4.6 was released ~4.5 years ago, so it would be also interesting to test it on newer compilers - GCC 4.9.x or 5.x, or some new

If you pull from git and then: ./autogen.sh ./configure cd microbench/ make ./benchmark_residual you will get something like this (armhf with gcc-4.9.3): shift order 2 : 0.000279 0.000284 0.000285 0.000525 mult order 2 : 0.000240 0.000242 0.000243 0.000247 shift order 3 : 0.000408 0.000413 0.000412 0.000415 mult order 3 : 0.000438 0.000443 0.000443 0.000445 shift or...

Hi, This patchet allows a few targets to be disabled when unrequired. The rational is coming from VLC's contrib buildsystem, so far we use make -C to select only some subparts of the available targets. It would be easier and cleaner to use autoconf to do so IMHO. There's an additional patch which fixes the build when building for WinRT/UWP platform, upstreamed from VLC. We have a couple
