Kinda depends where it's coming from. Could be newlib, could be cygwin,
could be sort itself. Either the + and - zeros aren't being correctly
converted to their float representations, or the comparison of + vs. - zero
isn't working right, at a first guess.

Hacky work-around: " | sort -r | sort [-n|-g] -s". First alphabetic sort
using -r gets all the negative numbers at the start of the list, then adding
stable flag to the numeric sort preserves their relative ordering when they
compare equal.
