strtod() problem - bug in library?

[Brian Fitzgerald]

String-to-decimal conversion problem on AIX/370
------ -- ------- ---------- ------- -- -------

When a string equivalent to zero containing no decimal
point is encountered, strtod() does not store a pointer to
the unconverted suffix.  Instead, it stores the same
pointer that was supplied, as though the conversion were
unsuccessful.

The AIX strtod() man page says that the decimal point is
optional.

Is my strtod function broken, is my code wrong, or am I
trying to do something non-portable or undefined?

If IBM has a bug fix, and you know the bug id number, or if
you have heard of this before, please send me e-mail or
post to this newsgroup.  Thanks in advance.
