John,
Here is the e-mail I got back from Synopsys their bug. Hope this helps.

Hi Paul,
Thanks for pointing out the problem. The while loop is the workaround to
ensure that compilation only start when you have access to DesignWare
Foundation license. I have forwarded your request to Foundation R&D team
and fix will be available ASAP. We are introducing one more dc_shell
variable which will act exactly like while loop. If you set
synlib_wait_for_design_license = {"DesignWare-Foundation"}
Then the DC compile, read, elaborate commands will wait for DesignWare
Foundation rather than aborting the process. The default value of this
variable is empty list. This feature will be available in 1998.08
Synopsys release.
Again set
synlib_wait_for_design_license = {"DesignWare-Foundation"}
to cause Design Compiler to wait for a DesignWare-Foundation license to
become available before proceeding with compile.
