I think the following would make sense to include:

2013-02-25  Niels Möller  <nisse at lysator.liu.se>

	* mini-gmp/tests/t-double.c (testmain): Declare double variables
	as volatile, to drop extended precision.

	* mini-gmp/tests/testutils.c (testfree): New function. Use it
	everywhere where test programs deallocate storage allocated via
	the mini-gmp allocation functions, including uses of mpz_get_str
	for various test failure messages.

IIRC, the second change fixes crashes when displaying messages about
failing tests.

2013-02-19 Marco Bodrato <bodrato at mail.dm.unipi.it>

	* mini-gmp/mini-gmp.c: Move asserts to work-around a compiler bug.

	* mini-gmp/tests/t-reuse.c: Fix typo causing the same negation condition
	to be applied to all operands. (See 2013-02-03, Torbjorn)

/Niels
