strtold?

[Howland Craig D (Craig)]

Corinna:
     I don't have any answers as to why strtold is not generally
available, but I vote that it should be made so (at least after
adequate testing), as long double support is almost completely
lacking.
     This raises some general questions that I have regarding long
double.  This email will be followed by another with a new subject
("long double (was "strtold?")") to raise them, since perhaps it is
best to track them separately.

Subject: strtold?

Hi,

I'm just implementing wscanf and friends.  While I'm at it, I'm
stumbling over the missing wcstold functionality.  Strange enough,
newlib has a strtold function in libc/stdlib/ldtoa.c.  However, that
function is actually called _strtold and not mentioned in the header
files at all.  But it's used in vfscanf.c.

Here's the question:  Why is strtold not "officially" exported when
the function is actually available?  Is there any good reason?
If not, I'd suggest to declare strtold in stdlib.h.  Then I could
implement wcstold along the lines of the current wcstod function and
we would get long double support in wscanf more or less for free.
