# Based on the setting of environment variable `HDF5_MODE' we set the
# compiler flags unless they're already set.  Its value can be one or
# more of the following words:
#
#	$warn	    -- Generates compiler warnings.  You should always
#	               include this since it has no effect on the speed of
#	               the code produced.
#
#	$debug      -- Compiles in code to check for invariant conditions
#	               and turns on the `-g' flag for interactive
#	               debugging.  It also turns off seek optimizations in
#                      the low-level file driver.  This version of the
#                      library can be significantly slower than a production
#                      version.
#
#       $production -- Compiles an optimized version of the library
#       	       and disables code that checks for invariant
#       	       conditions.  It also turns on various optimizations
#                      such as seek optimizations in the low level file
#                      driver.
#
#       $profile    -- Compiles code with the `-pg' flag which
#       	       produces a `gmon.out' file when the library
#       	       runs. The gprof(1) command can read that file
#       	       and produce detailed run-time statistics.
#
# If HDF5_MODE is undefined then we use the value 
#
#	$debug $warn -DH5F_LOW_DFLT=H5F_LOW_SEC2
#
