+# This file is part of the HDF5 build script. It is processed shortly
+# after configure starts and defines, among other things, flags for
+# the various compile modes.

+# Compiler flags. The CPPFLAGS values should not include package debug
+# flags like `-DH5G_DEBUG' since these are added with the
+# `--enable-debug' switch of configure.
+#----------------------------------------------------------------------------
+
+
+# Choosing a C Compiler
+# ---------------------
+#
+# The user should be able to specify the compiler by setting the CC
+# environment variable to the name of the compiler and any switches it
+# requires for proper operation. If CC is unset then this script may
+# set it. If CC is unset by time this script completes then configure
+# will try `gcc' and `cc' in that order (perhaps some others too).
+#
+# Note: Code later in this file may depend on the value of $CC_BASENAME
+# in order to distinguish between different compilers when
+# deciding which compiler command-line switches to use. This
+# variable is set based on the incoming value of $CC and is only
+# used within this file.

+# C Compiler and Preprocessor Flags
+# ---------------------------------
+#
+# Flags that end with `_CFLAGS' are always passed to the compiler.
+# Flags that end with `_CPPFLAGS' are passed to the compiler when
+# compiling but not when linking.
+#
+# DEBUG_CFLAGS Flags to pass to the compiler to create a
+# DEBUG_CPPFLAGS library suitable for use with debugging
+# tools. Usually this list will exclude
+# optimization switches (like `-O') and include
+# switches that turn on symbolic debugging
+# support (like `-g').
+#
+# PROD_CFLAGS Flags to pass to the compiler to create a
+# PROD_CPPFLAGS production version of the library. These
+# usualy exclude symbolic debugging switches
+# (like `-g') and include optimization switches
+# (like `-O').
+#
+# PROFILE_CFLAGS Flags to pass to the compiler to create a
+# PROFILE_CPPFLAGS library suitable for performance testing (like
+# `-pg'). This may or may not include debugging
+# or production flags.
+#
+# CFLAGS Flags can be added to this variable which
+# might already be partially initialized. These
+# flags will always be passed to the compiler
+# and should include switches to turn on full
+# warnings. HDF5 attempts to be ANSI and Posix
+# compliant and employ good programming
+# practices resulting in few if any
+# warnings.
+#
+# Warning flags do not have to be added to CFLAGS
+# variable if the compiler is the GNU gcc
+# compiler or a descendent of gcc such as EGCS or PGCC.
+#
+# The CFLAGS should contains *something* or else
+# configure will probably add `-g'. For most
+# systems this isn't a problem but some systems
+# will disable optimizations in favor of the
+# `-g'.
+#
+#
+# These flags should be set according to the compiler being used.
+# There are two ways to check the compiler. You can try using `-v' or
+# `--version' to see if the compiler will print a version string. You
+# can use the value of $CC_BASENAME which is the base name of the
+# first word in $CC (note that the value of CC may have changed
+# above).
