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. +# +# also: 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 AX_CFLAGS_IRIX_OPTION +# +# LAST MODIFICATION +# +# 2006-12-12 +# +# COPYLEFT +# +# Copyright (c) 2006 Guido U.
