# 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
#   ax_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.
