Test suite bug...?

["David Termohlen" <Termohlen dot David at oscsystems dot com>]

I'm not sure if this is a bug... but it sure looks ugly...

Looking for a validation for sin/cos, I came accros your test suite.  In file
921206-1.c "smap" is never initialized and the index "l" is allowed to go
negative.

Also, the test does not check the full range of (un normalized) values sent to
"sin".  In short, it looks like this routine has never been used...  Do y'all
have another set of routine to validate trig functions?
