Subject: More float test and portability fixes.

Avoid assuming exact results in tstypes test; some platforms vary.
(per buildfarm members eulachon, danio, lapwing)

Avoid dubious usage (inherited from upstream) of bool parameters to
copy_special_str, to see if this fixes the mac/ppc failures (per
buildfarm members prariedog and locust). (Isolated test programs on a
ppc mac don't seem to show any other cause that would explain them.)
