Will these reports ever end? ;-)

I bet he tried to compile GMP 4.3.2 (with GCC 5.2).


Oscar, please use a recent version of GMP;  the test suite (i.e.,
t-scan) of the completely outdated GMP 4.3.2 contains a subtle bug such
that it'll fail with any GCC version >= 4.8.0.  It has been fixed years
ago, but the GCC guys still "recommend" that dead old, version.  (More
precisely, GCC's prerequisites page says "GMP 4.3.2 *or later*", but
their "GCC infrastructure" folder still only offers that version, dated
February 1st, 2010(!).  While it is indeed sufficient to /bootstrap
GCC/, and the library itself isn't affected by the bug, you'll certainly
want to use a more current one.)
