#
# SYNOPSIS
#
# AX_CFLAGS_IRIX_OPTION (optionflag [,[shellvar][,[A][,[NA]]])
#
# DESCRIPTION
#
# AX_CFLAGS_IRIX_OPTION(-go_for_it) would show a message as like "checking
# CFLAGS for irix/cc -go_for_it ... 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_IRIX_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.
