should I check in a fix for this?

the code in PyFloat_FromString contains lots of trickery to deal with more or less
broken literals, and more or less broken C libraries.

unfortunately, and unlike most other functions with similar names, PyFloat_FromString
takes a Python object, not a char pointer.  would it be a good idea to add a variant
that takes a char*?  if so, should PyFloat_FromString use the new function, or are we
avoiding that kind of refactoring for speed reasons these days?

any opinions?
