+Details:
+  For mpfr_sin, the exponent range was not restored, and restoring it
+  before calling mpfr_sincos_fast as this was done for mpfr_cos did
+  not work; indeed the source of this function shows that it needs an
+  extended exponent range. So, changed both mpfr_cos and mpfr_sin to
+  call mpfr_sincos_fast in the extended exponent range and restore the
+  exponent range at the end, like in usual code.

+Various fixes, improvements and new tests concerning the exponent range
+and exceptions (flags). Details:
+
+[src/set_q.c]
+  * Added missing MPFR_SAVE_EXPO_FREE in case of preliminary overflow
+    or underflow (extreme cases).
+  * Replaced a "return" by MPFR_RET: this is at least needed in the
+    extreme case cd != 0, and safer in general.
+
+[src/{ui_div.c,ui_sub.c}] Correction for reduced exponent range.
+
+[tests/tgeneric.c] Major clean-up, with some minor corrections.
+Added support for unsigned long argument, which can be the first
+or the second one (another intent is to replace tgeneric_ui.c,
+which does fewer tests concerning the flags).
+
+[tests/t{add,div,mul,sub}_ui.c] Replaced tgeneric_ui.c by tgeneric.c,
+showing the mpfr_mul_ui bug fixed in r9516 (missing inexact flag).
+
+[tests/tpow_all.c] Better flags output in error message.
+
+[tests/tset_q.c] Check the flags.
+
+[tests/{tui_div.c,tui_sub.c}] Added generic tests, yielding assertion
+failures without the above fix when assertions are checked. Added a
+new test checking overflow.

+of magnitude of 1 for half outputs. This will be useful for mpfr_rint_*
+tests.
+
+For tgeneric.c, the value of this argument is controlled by a new macro
+TEST_RANDOM_ALWAYS_SCALE (0 by default, which corresponds to the current
+behavior). For the other tests that call tests_default_random(), the
+argument is set to 0, so that the behavior remains the same.

+Test suite improvement with Automake 1.13.
+  * Moved GMP version check from tversion.c to the test_version()
+    function of tests.c, so that this check is done in every test.
+    This function now returns an int, as there are now 3 cases:
+    1. An error in MPFR version check is a fatal error: test_version()
+       exits with an error (exit status = 1).
+    2. An error in GMP version check is a non-fatal error: if there
+       are no errors in MPFR version check, test_version() returns
+       with value 1.
+    3. Otherwise test_version() returns with value 0 (everything is
+       fine).
+  * tversion.c still runs test_version(), but fails if this function
+    returns with an error, i.e. any error is fatal for this test.
+    Note: for the other tests, one just has a message in the output
+    in case of GMP version mismatch.
+  * mpfr-test.h: updated test_version() prototype.
+  * Makefile.am: removed the second tversion invocation, and output
+    the contents of tversion.log if this file exists (typically with
+    Automake 1.13+, for which one no longer gets tversion output by
+    default).

+[src/mpfr-impl.h] Decimal point / thousands separator support can now be
+  detected automatically by configure (from the presence of <locale.h>
+  and the above members) or explicitly disabled/enabled by the user by
+  defining the MPFR_LCONV_DPTS macro to 0 or 1 via CFLAGS (a configure
+  switch might be added in the future).
+[tests/tsprintf.c] Do the locale_da_DK test only if MPFR_LCONV_DPTS is

+[tests/{tset_d.c,tget_flt.c}] Disabled two tests when HAVE_SIGNEDZ
+isn't defined, because these tests rely on signed zeros.
+Note: this is needed for compilers that don't support signed zeros,
+like tcc 0.9.26 and before.

+[src/{fits_u.h,fits_uintmax.c}] Fixed the mpfr_fits_u*_p functions,
+  which incorrectly returned 0 ("doesn't fit") on negative arguments
+  when the rounding to an integer was 0. The fits_uintmax.c file now
+  uses fits_u.h for consistency.
