You can override the shellvar-default of +# CFLAGS of course. The order of arguments stems from the explicit macros +# like AX_CFLAGS_WARN_ALL. +# +# The cousin AX_CXXFLAGS_GCC_OPTION would check for an option to add to +# CXXFLAGS - and it uses the autoconf setup for C++ instead of C (since it +# is possible to use different compilers for C and C++). +# +# The macro is a lot simpler than any special AX_CFLAGS_* macro (or +# ac_cxx_rtti.m4 macro) but allows to check for arbitrary options. +# However, if you use this macro in a few places, it would be great if you +# would make up a new function-macro and submit it to the ac-archive. +# +# - $1 option-to-check-for : required ("-option" as non-value) +# - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case) +# - $3 action-if-found : add value to shellvariable +# - $4 action-if-not-found : nothing +# +# Note: in earlier versions, $1-$2 were swapped. We try to detect the +# situation and accept a $2=~/-/ as being the old option-to-check-for. +# +# There are other variants that emerged from the original macro variant +# which did just test an option to be possibly added. However, some +# compilers accept an option silently, or possibly for just another option +# that was not intended. Therefore, we have to do a generic test for a +# compiler family. For gcc we check "-pedantic" being accepted which is +# also understood by compilers who just want to be compatible with gcc +# even when not being made from gcc sources. +# +# See also: AX_CFLAGS_SUN_OPTION, AX_CFLAGS_HPUX_OPTION, +# AX_CFLAGS_AIX_OPTION, and AX_CFLAGS_IRIX_OPTION. +# +# LAST MODIFICATION +# +# 2008-04-12 +# +# COPYLEFT +# +# Copyright (c) 2008 Guido U.
