I can't believe I forgot that Jessica had sent this in and that you had
replied to it.  I tried the patch refered to in msg00241.html.  I think
it works OK, I completely removed the strtoll and strtoull definitions
from config/os/hpux/bits/os_defines.h and applied that patch and built.

I am having some problems creating a test program though, I tried:

#include <cstdlib>
int main()
{
        long long i;
        long j;
        i = std::strtoll("123",(char **) 0, 10);
        j = std::strtol("123",(char **) 0, 10);
        exit(0);
}

and got:

str.cc: In function `int main()':
str.cc:6: `strtoll' undeclared in namespace `std'

I think this is OK since strtoll in cstdlib is under
#if _GLIBCPP_USE_C99
but I don't know how to write a program that uses it
though.  I tried --std=c99 but that created more errors.

I did verify that strtoll and strtoull were created in libiberty and
called from libstdc++.

Where do we go from here?
