Hi C++'ers,

I need a cross-platform C++ method of converting strings to eight byte
integers.
GNC g++ fully supports the (non-standard) "long long" integer size.
One can declare "long long" integers and g++ supports accessing
std::strtoll() and std::strtoull(), which I think are equivalent to
their C99 counterparts.
The other C++ compilers that I've tried (PGI pgCC and AIX xlC) support
"long long" but do not support std::strtoll() and std::strtoull() (at
least with the switches I've tried).
I need cross-platform strtoll() and strtoull()-functionality.

What is the recommended way to obtain this functionality in C++ now?
I have the BSD source code for strtoll.c so I can, as a last measure,
implement this function in my code, but I want to make sure I do so
in a sane way, e.g., in the way a future C++ standard would support
strtoll() and strtoull()-functionality. Would this be as
std::strtoll() or is some other method preferred?

Any advice appreciated,
Charlie
