+dnl @synopsis AX_CFLAGS_IRIX_OPTION (optionflag [,[shellvar][,[A][,[NA]]])
+dnl
+dnl AX_CFLAGS_IRIX_OPTION(-go_for_it) would show a message as like
+dnl "checking CFLAGS for irix/cc -go_for_it ... yes" and adds the
+dnl optionflag to CFLAGS if it is understood. 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. We try to detect the
+dnl situation and accept a $2=~/-/ as being the old
+dnl option-to-check-for.
+dnl
+dnl see also: AX_CFLAGS_GCC_OPTION for the widely used original
+dnl variant.
