+# 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 (be sure to use single quotes when
+# setting its value or the dollar signs will be expanded as variables
+# too soon):
+#
+# $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.
+#
+# $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
+#
+
+# Unconditionally set the compiler to gcc since the following flags
