1# =========================================================================== 2# http://www.gnu.org/software/autoconf-archive/ax_cflags_aix_option.html 3# =========================================================================== 4# 5# SYNOPSIS 6# 7# AX_CFLAGS_AIX_OPTION (optionflag [,[shellvar][,[A][,[NA]]]) 8# 9# DESCRIPTION 10# 11# AX_CFLAGS_AIX_OPTION(-qubicle) would show a message as like "checking 12# CFLAGS for aix/cc -qubicle ... yes" and adds the optionflag to CFLAGS if 13# it is understood. You can override the shellvar-default of CFLAGS of 14# course. The order of arguments stems from the explicit macros like 15# AX_CFLAGS_WARN_ALL. 16# 17# The cousin AX_CXXFLAGS_AIX_OPTION would check for an option to add to 18# CXXFLAGS - and it uses the autoconf setup for C++ instead of C (since it 19# is possible to use different compilers for C and C++). 20# 21# The macro is a lot simpler than any special AX_CFLAGS_* macro (or 22# ax_cxx_rtti.m4 macro) but allows to check for arbitrary options. 23# However, if you use this macro in a few places, it would be great if you 24# would make up a new function-macro and submit it to the ac-archive. 25# 26# - $1 option-to-check-for : required ("-option" as non-value) 27# - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case) 28# - $3 action-if-found : add value to shellvariable 29# - $4 action-if-not-found : nothing 30# 31# note: in earlier versions, $1-$2 were swapped. We try to detect the 32# situation and accept a $2=~/-/ as being the old option-to-check-for. 33# 34# see also: AX_CFLAGS_GCC_OPTION for the widely used original variant. 35# 36# LICENSE 37# 38# Copyright (c) 2008 Guido U.
