Automake version upgrade Description: Upgraded automake version from 1.6.2 to 1.9.5. Changed bin/reconfigure script to use automake 1.9.5. Changed configure.in and Makefiles to use new FCFLAGS and FC variables instead of FFLAGS and F9X. Automake and configure should now do the lion's share of the work supporting Fortran 9X; macros in acsite.m4 are now mostly unused (will be cleaned later). Altered how configure handles pmake; now root-level Makefile.in is processed by bin/reconfigure to have a .MAKEFLAGS target, since automake no longer allows us to define unused variables. Configure now always checks for C++ compiler even if it is not used, since automake thinks this is the Right Thing To Do and will break otherwise. Platforms tested: Sol, copper, heping, mir, sleipnir, eirene, pommier, kelgia, modi4.

# 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
