Hi everyone,

I've tried to install Etherlab 1.3-r589 under Ubuntu 9.10 but
the configure script kept failing with the following error:

checking whether make sets $(MAKE)... yes
checking RTAI path... /usr/realtime
./configure: line 7056: syntax error near unexpected token `;;'
./configure: line 7056: `ac_tool_warned=yes ;;'

After poking around a bit I was able to fix this by changing
the part that reads out the ipipe configuration from kernel
config in configure.ac:

@@ -141,8 +141,7 @@ ipipe_conf=$(make -s -f - -I${linux_dir}
  include .config
  	@echo -n $(CONFIG_IPIPE)
  test "x${ipipe_conf}" == "xy" || \
      AC_MSG_ERROR(not configured)

After running bootstrap the configure, make, make install
is working again.
Maybe this is a >=bash-4.0 problem. If someone else
encounters this, a patch is attached.
