+# SYNOPSIS
+#
+#   AX_CFLAGS_AIX_OPTION (optionflag [,[shellvar][,[A][,[NA]]])
+#
+# DESCRIPTION
+#
+#   AX_CFLAGS_AIX_OPTION(-qubicle) would show a message as like
+#   "checking CFLAGS for aix/cc -qubicle ... yes" and adds the
+#   optionflag to CFLAGS if it is understood. 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_AIX_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.
+#
+#   see also: AX_CFLAGS_GCC_OPTION for the widely used original
+#   variant.
