The worst-case precision is massively improved - as I noted in the 
original patch submission, the testcases added by the patch showed (on 
x86_64) errors of up to 203 ulp for float, 1713 ulp for double and 12714 
ulp for long double.  It only appears as a decrease in precision because 
the testsuite coverage for tgamma was previously so limited.

If those trace back to missing underflows from atanl / atan2l (if the part 
of the result of casinh / casin that should underflow is the one computed 
by atan2l), then that's another instance of bug 15319, in which case you 
could change them to UNDERFLOW_EXCEPTION_OK and add a comment like the 
existing instances of

    /* Bug 15319: underflow exception may be missing.  */

(if they trace to some other cause, a separate bug should be filed).
