Ah, I see. Sorry, I had not seen this detail.
Find attached the results on a dozen of platforms.
I integrated these test results into test-strtod.c as comments (since we don't
yet have a matrix like in m4/printf.m4), using a script like this:

Then I also updated the doc accordingly. Notable disagreements:
- I could not see an indication of the "returns a wrong end pointer on some
platforms: Solaris 2.4" problem, so I removed this;
- You seem to have seen problems on Solaris 8 that I did not see. What can
be the reason? Did you use gnulib's signbit and isnan functions? I used
the ones from the system, or trivial platform-specific replacements.
- Changed wording: 0.0 is not considered a "positive value". The usual
definition of "positive" is "x > 0", and "negative" is "x < 0". Yes, a
"negative zero" is not negative; that's actually a misnomer.
