Patch 1 adds a check for the compilers visibility macro to configure.ac. Patch 2 avoids redefined symbol errors in clang of the tls entry points. Based on a suggestion from Rafael Ávila de Espíndola <rafael.espindola at gmail.com> in http://llvm.org/bugs/show_bug.cgi?id=19778. Tested with gcc 4.9 and clang 3.6(rc) Marc Dietrich (2): configure: add visibility macro detection to configure
