float stuff again

[Benjamin Kosnik]

John, Jeff Law recently did some work to support elements of C99 for HPUX.

See:

2002-01-03  Jeffrey A Law  <law@redhat.com>

        * config/os/hpux/bits/os_defines.h: Prefix __strtoll and
        __strtoull declarations with __extension__.

And others in the libstdc++-v3/ChangeLog. You might want to check out the 
contents of that file.

It looks like HPUX 11 headers are not C99 compliant, but support for some 
of the issues could be hacked in. I'm not super-sure this is such a great 
idea, but if you can do it cleanly, well then. I'm all for it.

Many? Perhaps. Are they in the correct header files? Are the signatures 
exactly correct?

Err. I'm skeptical, given the problems Jeff had just getting strtoll, 
strtoull working.

best,
