Description:
testhdf5/select runs very slow when in --disable-production mode using
pgcc compiler. This was caused by the -Mchkfpstk compiler switch added
to the DEBUG_FLAGS in config/pgi-flags file.
Solution:
Removed -Mchkfpstk from both pgi-flags and pgi-fflags.
See Bug 2026 for dettails.
Tested: (no h5committest test since they don't use PGI compilers.)
Jam (linux32): using pgcc/pgf90/pgCC using default and --enable-production.
Amani (linux64):
using pgcc/pgf90/pgCC (32 bits mode by "-tp k8-32"), using default and --enable-production.

Reduce compiler optimizations for v10.6, to work around bug with static
constant char *'s.
Tested on:
Linux/32 2.4 (jam) w/PGI

Bring PGI compiler flags from 1.8 branch, reducing optimization level with
PGI C 9.x
Tested on:
Linux/64 2.4 (amani) w/PGI C 9.x & 10.x

CFLAGS overhaul
Description:
Modified the way configure handles CFLAGS.
(note: all changes also apply to FCFLAGS, CXXFLAGS, CPPFLAGS, and LDFLAGS).
1. The configure process will now always preserve a user's CFLAGS
environment variable setup. Any additional flags necessary for compilation
added at configure time will be passed into the Makefiles as AM_CFLAGS,
which is an automake construct to be used in addition to CFLAGS.
This will allow a user to have the final say, as CFLAGS will always appear
later in the compile line than AM_CFLAGS. Additionally, setting CFLAGS
during make will no longer completely erase all flags set by configure,
since they're maintained in AM_CFLAGS.
2. Additionally, where possible, flags previously being assigned directly
into CFLAGS (and thus propagating into h5cc) have now been redirected into
H5_CFLAGS, so they're used ONLY for compiling hdf5, and not embedded into
the h5cc wrapper script as well.
*Note that H5_CFLAGS ultimately is assigned into AM_CFLAGS for use in the
Makefiles. Complete description of changes and build process will be
included in a Configure Document that Elena and I are working on.
3. Removed unsupported config files. This includes:
config/dec-osf*
config/hpux11.00
config/irix5.x
config/powerpc-ibm-aix4.x
config/rs6000-ibm-aix5.x
config/unicos*
4. Modified configure summary to display additional values. Specifically,
appropriate AM_* variables are being shown, as well as H5_FCFLAGS and
H5_CXXFLAGS, which were for some reason not already present.
Tested:
- H5committest
- Tested on all THG / NCSA machines, using several combinations of the more
prominent configure options (c++, fortran, szip, threadsafe, parallel,
et cetera). (Thanks to Quincey for rysnc testing setup!)
- With regards to new automated testing, anything *necessary* for
compilation will be caught by the daily tests as it stands now. (i.e.,
if LDFLAGS is not properly set when szip is used, linking will fail).
Additionally, with regards to which flags get into h5cc, if any
*necessary* flags have been improperly removed, then daily tests should
fail during make installcheck. Additional machine-specific desired
behaviors and/or checks may have to be set up separately within the
daily tests, so this is something to work on.

Description:
Add source code copyright notice; comment symbols vary by type of file.
Platforms tested:
No changes that should cause any problems. Nonetheless, the tree will
be checked out fresh and tests run immediately post-commit.

Bug fix
Description:
When mpicc/mpif90 is a wrapper around a PGI compiler, turn on less
agressive optimization options to avoid testing errors.
Platforms tested:
Linux 2.4 (verbena)
Too minor to require h5committest

Code cleanup/bug fix
Description:
Remove the undocumented "$NOFP" shell variable which would allow production
builds without removing the stack frame. This was cascading between C and
FORTRAN builds and causing problems.
Solution:
Hard-code removing the stack frame for now. Users would have needed to
read the configure scripts anyway, so there's not really much benefit to the
extra knob. Users who need this functionality (production builds with stack
frames) are debugging probably, so they will need to modify the script and
build their own version of the library now.
Platforms tested:
Linux 2.4 (verbena)
Too minor to require h5committest

Bug fix
Description:
Tweak PGI compiler auto-detection to work for version 5.0 compilers as
well as version 5.2 compilers.
Platforms tested:
Linux 2.4 (verbena) w/PGI compilers
Not tested with rest of h5committest platforms
