# =========================================================================== # https://www.gnu.org/software/autoconf-archive/ax_append_flag.html # =========================================================================== # # SYNOPSIS # # AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE]) # # DESCRIPTION # # FLAG is appended to the FLAGS-VARIABLE shell variable, with a space # added in between. # # If FLAGS-VARIABLE is not specified, the current language's flags (e.g. # CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains # FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly # FLAG. # # NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. # # LICENSE # # Copyright (c) 2008 Guido U.
