I've attached the Makefile.global from the system, in case it's of use.

I believe that this will result in Slony not working on AIX.

Not an option, we don't have cc_r on the server.

# Automatic dependency generation
# -------------------------------
# When we configure with --enable-depend then we override the default
# compilation rule with the magic below. While or after creating the
# actual output file we also create a dependency list for the .c file.
# Next time we invoke make we will have top-notch information about
# whether this file needs to be updated. The dependency files are kept
# in the .deps subdirectory of each directory.
#
# The sed command is necessary to post-process the dependency file:
# Each dependency file becomes a target of its own, without
# dependencies or commands. This is because if you happen to remove a
# file that is a dependency (say, you rename a header file) the
# dependency would point to a non-existing file and make would fail.
# But if the file is listed as a target of its own, without
# prerequisites and commands, and doesn't exist then make will
# consider it updated. (That in turn also has the nice side effect
# that make will update all files that depended on the now removed
