Optional features:
# - $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.
-#
# There are other variants that emerged from the original macro variant
# which did just test an option to be possibly added. However, some
# compilers accept an option silently, or possibly for just another option
# also understood by compilers who just want to be compatible with gcc
# even when not being made from gcc sources.
#
+# This version has been modified by Vincent Bernat <bernat@luffy.cx>
+# to ensure that the shell variable the option is added to is
+# prepended to the test variable (like a regular CFLAGS).
+#
# See also: AX_CFLAGS_SUN_OPTION, AX_CFLAGS_HPUX_OPTION,
# AX_CFLAGS_AIX_OPTION, and AX_CFLAGS_IRIX_OPTION.

# modified version of the Autoconf Macro, you may extend this special
# exception to the GPL to apply to your modified version as well.

# SYNOPSIS
#
-# AX_LD_CHECK_FLAG(FLAG-TO-CHECK,[PROLOGUE],[BODY],[ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
+# AX_LDFLAGS_OPTION(FLAG-TO-CHECK,[VAR])
#
# DESCRIPTION
#
-# This macro tests if the C++ compiler supports the flag FLAG-TO-CHECK. If
-# successfull execute ACTION-IF-SUCCESS otherwise ACTION-IF-FAILURE.
-# PROLOGUE and BODY are optional and should be used as in AC_LANG_PROGRAM
-# macro.
-#
-# Example:
-#
-# AX_LD_CHECK_FLAG([-Wl,-L/usr/lib],[],[],[
-# ...
-# ],[
-# ...
-# ])
+# This macro tests if the C compiler supports the flag FLAG-TO-CHECK. If
+# successfull add it to VAR.
#
# This code is inspired from KDE_CHECK_COMPILER_FLAG macro. Thanks to
# Bogdan Drozdowski <bogdandr@op.pl> for testing and bug fixes.
#
+# This version has been (heavily) modified by Vincent Bernat
+# <bernat@luffy.cx> to match AX_CFLAGS_GCC_OPTION.
