    5 # SYNOPSIS
    6 #
    7 #   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
    8 #
    9 # DESCRIPTION
   10 #
   11 #   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
   12 #   added in between.
   13 #
   14 #   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
   15 #   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
   16 #   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
   17 #   FLAG.
   18 #
   19 #   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.
