 - from Kevin Ryde <user42@zip.com.au>:
    Determine the exp2/exp3 thresholds using tune/tuneup.c.
 
-- problems when mpfr uses a different compiler (gcc) than gmp (for example
-	cc under Solaris 2.7).
+Changes in existing functions:
+
+- invert 2nd and 3rd arguments of mpfr_round_prec (to be coherent with
+	mpfr_set_prec)
+- merge mpfr_inp_str and mpfr_set_str (cf glibc sscanf/fscanf)
 
 New functions to implement:
 
 - those from LIA: missing secant, cosecant, cotangent (trigo/hyperbolic)
 - nextafter/nextforward : X + epsilon if X < Y, X - epsilon if X > Y
 - nextabove/nextbelow ?
+- mpfr_get_exp / mpfr_set_exp

 Rounding:
 
+- mpfr_pow -> loops when exact (for example 4^(1/2)).
+- mpfr_pow isn't completely specified (concerning signed zeros).
+
 Efficiency:
 
+- implement range reduction in sin/cos/tan for large arguments
+	(currently too slow for 2^1024)
+- mpfr_asin/acos are too slow for small values (2^(-1021) for example)
+- idem for mpfr_atanh (2^(-1021) for example)

 - rename mpf2mpfr.h to gmp-mpf2mpfr.h?

-- some comparison functions aren't completely specified (concerning NaN).
-  Add new comparison functions (eq, ne, lt, gt, le, ge)?
+- use GMP rand/srand functions instead for SEED_RAND (time(NULL)). Kevin:
+  GMP tests/misc.c has a scheme to print the seed chosen and allow for a
+  re-run with a given seed.  If you moved towards _gmp_rand and friends
+  at some stage you could probably use that scheme almost unchanged.
+  An advantage of _gmp_rand of course is that it's the same on all
+  systems, apart from limb size, so you're not at the mercy of random or
+  lrand48, etc.
