# AIX 5.x using the IBM C Set++ compiler.
#
# NOTE! IBM is no longer supporting AIX at any version earlier than 4.3,
# and Riverace is not testing or supporting ACE on them either. No steps
# have been taken to intentionally disable anything, but it is not being
# tested either.
#
# NOTE 2! This file is only for use with the older CSet++ compiler, which
# IBM doesn't sell or support any longer. Riverace doesn't support ACE
# with it either. This file is still here in case there is some site
# still using the old compiler, but it is completely unsupported.
#
# On 4.1, this file assumes that the user has installed the AIX patch
# containing the dl*() APIs.  To use these APIs, IBM has created a
# separate product (free to AIX licensees) called shared library
# hookable symbols (or slhs/6000).  If they don't have this patch, the
# sv* commands for compiling and linking will not be present on the
# system.
#
# On 4.2, the AIX fileset bos.rte.bind_cmds must be at version 4.2.0.2 or
# higher in order to build libACEshr.a, and at 4.2.0.4 or higher for dl*()
# routines to work properly. Best to apply the update available at:
# ftp://service.boulder.ibm.com/aix/fixes/v4/os/bos.rte.bind_cmds.4.2.0.4.bff
# or a successor.
