[Maxima] New testsuite failures in CVS HEAD

[David Ronis]

I just upgraded using CVS HEAD, built (no complaints), and ran the
testsuite.  All went well except towards the end I got:

Running tests in rtest_round: 
********************** Problem 79 ***************
Input:
truncate(- x)


Result:
- 3.141592653589793

This differed from the expected result:
- %pi

********************** Problem 81 ***************
Input:
round(- x)


Result:
- 1.732050807568877

This differed from the expected result:
- sqrt(3)

93/95 tests passed.

The following 2 problems failed: (79 81)

Was I really supposed to get the symbolic constants?  The numbers seem
correct.
