So far, I haven't encountered this problem yet.

Trying to create a hurd image with this patch set, but mpfr fails for
me.

Error in mpfr_vsprintf (s, "%0+ -'13.10Pd:", ...);
expected: "+01,234,567  :"
got:      "+0001,234,567:"

Updating to 4.2.1 (see attached patch) seems to fix it for me.

Greetings,
