Hi all,
A recent upgrade of the IBM machines at NCAR has broken CAM versions
2.0.1 and earlier.
Thanks to Brian Eaton for the work-around (see below).
Please note that this work-around is in the development version and will
be included in the CAM 2.0.2 release.

Subject: makefile fix
It appears that a recent "upgrade" of some systems software on
blackforest is causing the current CAM code (2.0.1) to fail (and most
likely earlier CAM versions as well). The fix is to edit the Makefile
(cam_root/models/atm/cam/bld/Makefile) and change the optimization from
"-O3 -qstrict" to "-O2 -qmaxmem=-1". To do this look for the AIX section
of the Makefile which starts with the following lines:
#------------------------------------------------------------------------
# AIX
#------------------------------------------------------------------------
Look below that (about 40 lines) for the lines
else
# Inline when not debugging
FFLAGS += -O3 -qstrict -Q
and change to
else
# Inline when not debugging
FFLAGS += -O2 -qmaxmem=-1 -Q
