# SYNOPSIS
#
# AX_PROG_YASM_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
#
# DESCRIPTION
#
# Makes sure that yasm supports the version indicated. If true
# the shell commands in ACTION-IF-TRUE are executed. If not the shell
# commands in ACTION-IF-FALSE are run. Note if $YASM is not set
# (for example by running AX_WITH_PROG) the macro will fail.
#
# Example:
#
# AX_WITH_PROG(YASM,yasm)
# AX_PROG_YASM_VERSION([1.1.1],[ ... ],[ ... ])
