Library error messages with CCS generated basic project for TMS320C6713

Other Parts Discussed in Thread: TMS320C6727

I recently downloaded  Code Composer Studio Version: 5.3.0.00090. I am starting with a basic project built by 'Project->New CCS Project' I select "Empty Project(with main.c)". Select the TMS320C6713 as the variant. Project is created. First build, I get these errors:

warning #10366-D: automatic library build: using library "C:\ti_5_3\ccsv5\tools\compiler\c6000_7.4.1\lib\rts6700.lib" for the first time, so it must be built. This may take a few minutes.
error: function _sin in file sin.c : invalid instruction schedule generated;
try reducing speed optimization levels
error: function _tanh in file tanh.c : invalid instruction schedule generated;
try reducing speed optimization levels

I have made no changes to this point. Is there anything I should be concerned with?

BTW, a TMS320C6727 target did not produce these errors best I recall.
