Automake version upgrade
Description:
Upgraded automake version from 1.6.2 to 1.9.5.
Changed bin/reconfigure script to use automake 1.9.5.
Changed configure.in and Makefiles to use new FCFLAGS and FC variables
instead of FFLAGS and F9X.
Automake and configure should now do the lion's share of the work
supporting Fortran 9X; macros in acsite.m4 are now mostly unused (will
be cleaned later).
Altered how configure handles pmake; now root-level Makefile.in is
processed by bin/reconfigure to have a .MAKEFLAGS target, since
automake no longer allows us to define unused variables.
Configure now always checks for C++ compiler even if it is not
used, since automake thinks this is the Right Thing To Do and
will break otherwise.
Platforms tested:
Sol, copper, heping, mir, sleipnir, eirene, pommier, kelgia, modi4.
Bug fix
Description:
Add special-case handling to floating-point conversion tests to avoid
problems with denormalized values on Cray T3E & T90 platforms. (Still not
working on Cray SV1, but at least it's closer).
Solution:
Detect denormalized values and don't try to operate on them on the Crays.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Cray T3E (hubble.cray.com)
Cray T90 (gypsy.cray.com)
Bug Fix
Description:
The FFLAGS, CXXFLAGS, and CPPFLAGS variables weren't carrying
user-defined values into the Makefiles.
Solution:
Changed the flags from FOO="..." to FOO="$FOO ..."
Platforms tested:
Copper
Verbena
Arabica

Update
Description:
Revamped the configuration system. The configurations for the Fortran
and C++ libraries are no longer separate from the "main"
configuration system. This involved removing the "configure*" and
"aclocal.m4" files from the fortran/ and c++/ subdirectories. Also
merging settings in the config/ subdirectories into the main config/
subdirectory.
Fortran header files had to be modified a little for Linux. It was
checking if it was a Linux machine by some #defines, however with the
-std=c99 switch, these defines weren't there. I added a check for
some other ones which should be there whether the -std=c99 switch is
used or not.
Platforms tested:
Verbena (Fortran & C++)
Sol (Fortran & C++)
Copper (Fortran & C++)
Modi4 (Parallel, Fortran, & C++)
Misc. update:
New platform
Description:
Support the Cray SV1 machine. (config file is identical to unicosmk file
right now).
Platforms tested:
Cray SV1 (killeen.nersc.gov)
