Ouch - it looks like this platform parsed "inf" as a huge value, then
printed it as a finite value rather than infinity. I can't tell whether
the strtod misparsed inf, or whether it gave a valid infinite value which
was then mishandled by isinf(). Can you run 'make -k check' to see if it
at least passes gnulib tests? Can you run any further debugging on your
side, to see if you can spot where 'format(%010F,infinity)' starts
treating the value as a finite?
Hmm, a closer look at POSIX makes it appear that on non-IEEE machines, it
is feasible to not support infinity, in which case strtod("inf",NULL) must
fail with ERANGE and a value of HUGE_VAL. Does the hardware even support
IEEE infinities? If not, I need to correct the strtod tests to cater to
hardware that lacks infinity.

Don't work too hard, make some time for fun as well!
