#
# 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.
