Fair enough then. I'll buy that.

Okay, so the same commands are needed to build on QNX4 and QNX6?

On another point, this is the wrong place to set deplibs_check_method

+        qnx)
+          major=".$current"
+          versuffix=".$current"
+          deplibs_check_method="pass_all"
+          ;;
+

Please put it in libtool.m4 where it belongs.

Clean it up and resubmit, please submit patches for head and branch-1-5 if 
you can.

Thanks,
Peter
