-O3 flag causes compilation problems on most of the platforms with Intel compiler.
The problem exists in all vesrions of icc compiler up to the newest 9.1
Solution:
Use less agressive default setting O2 to avoid headache
Platforms tested: Linux 2.6 ia64 at UCAR (hal), cobalt (NCSA)

Platforms tested:
Tested in TG-NCSA, both production and development mode.

Description: For Intel 8.1 compiler, C99 standard has to be enabled to define macro ULLONG_MAX in its own header file limits.h.
Solution: Add flag -std=c99 to Intel compiler if the version is 8.1.
Platforms tested: Tested v1.6 because this is a very simple change.

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
