You can override the +dnl shellvar-default of CFLAGS of course. The order of arguments stems +dnl from the explicit macros like AX_CFLAGS_WARN_ALL. +dnl +dnl The cousin AX_CXXFLAGS_IRIX_OPTION would check for an option to add +dnl to CXXFLAGS - and it uses the autoconf setup for C++ instead of C +dnl (since it is possible to use different compilers for C and C++). +dnl +dnl The macro is a lot simpler than any special AX_CFLAGS_* macro (or +dnl ac_cxx_rtti.m4 macro) but allows to check for arbitrary options. +dnl However, if you use this macro in a few places, it would be great +dnl if you would make up a new function-macro and submit it to the +dnl ac-archive. +dnl +dnl - $1 option-to-check-for : required ("-option" as non-value) +dnl - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case) +dnl - $3 action-if-found : add value to shellvariable +dnl - $4 action-if-not-found : nothing +dnl +dnl note: in earlier versions, $1-$2 were swapped.
