The new AIX 4.3+ core support assumes a field in the core_dumpx
structure defined in /usr/include/sys/core.h that only exists in AIX 4.3.3
and not earlier releases. This prevents binutils from building on AIX
4.3.2. Albert and I have worked out the appended patch.

* rs6000-core.c: Use autoconf variable HAVE_ST_C_IMPL to guard use
of c_impl field.
* configure.in: Auto-configure HAVE_ST_C_IMPL.
* configure.in: Likewise.
