that both icc and gcc seem to reorder ordinary memory accesses around

191
* many: Install under "atomic_ops" instead of "ao".
192

193
files are all under include/atomic_ops.
194
Fix (hopefully) "make dist" in atomic_ops distribution.
195
Renamed various types to end in _t, though the old versions
196
are still defined for backward compatibility.

200
* ao_sysdeps/gcc/hppa.h: Define AO_CLEAR macro. Change
201
AO_pa_clearable_loc type. Add __ldcw, and __ldcw_align
202
helper macros. AO_test_and_set_full uses helper macros.
205
Started sometime after version 0.4 release. Currently the format is
206
informal. Eventually should become more GNU-like.
