Updated BUGS and TODO (mpfr_lgamma has been implemented, but see BUGS,

and gamma(-integer) with integer >= 1 is defined as NaN).

+* The implementation of mpfr_lgamma is incomplete (case x negative with
+  small exponent).
+
+* Incorrect behavior (possible infinite loop, e.g. in mpfr_exp2) in some
+  functions on tiny arguments, e.g. +/- 2^(emin-1), due to an integer
+  overflow in MPFR_FAST_COMPUTE_IF_SMALL_INPUT.
+
+* The mpfr_fma function behaves incorrectly if the multiplication overflows
+  or underflows. The overflow case has been fixed except in some corner
+  cases.

 Potential bugs:
 
 * Possible integer overflows on some machines.
