The previous setup failed with clang++ 3.0. * m4/stl.m4: New file. * configure.ac: Call AC_HEADER_UNORDERED_MAP, AC_HEADER_TR1_UNORDERED_MAP, and AC_HEADER_EXT_HASH_MAP. * src/misc/hash.hh: Include _config.h, and used the SPOT_HAVE_UNORDERED_MAP, SPOT_HAVE_TR1_UNORDERED_MAP, or SPOT_HAVE_EXT_HASH_MAP defines to decide which file to include.
