|
# SYNOPSIS
|
|
#
|
|
# AC_CHECK_DEFINE([symbol], [ACTION-IF-FOUND], [ACTION-IF-NOT])
|
|
# AX_CHECK_DEFINE([includes],[symbol], [ACTION-IF-FOUND], [ACTION-IF-NOT])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Complements AC_CHECK_FUNC but it does not check for a function but for a
|
|
# define to exist. Consider a usage like:
|
|
#
|
|
# AC_CHECK_DEFINE(__STRICT_ANSI__, CFLAGS="$CFLAGS -D_XOPEN_SOURCE=500")
