Bug fixes and tests



Okay, I'll work on this project---it should allow us to test
bug fixes on all platforms more readily. 

One semi-tedious thing is that some tests need an 'errcatch.'  Without the
errcatch, run_testsuite hangs.  For example, it seems that I need errcatch 

on the test

/* bug 990924 */
errcatch(is(equal((%E^(%I*z)-%E^-(%I*z)), 0)), prederror: false);
[false]$
