Hello List!

I'm having difficulty using the C++ std::string functions.

A search of README, problems.txt et al did not mention this

#include <stdlib.h> //This is a workaround for header errors <<
from the FAQ

#include <string>    // This includes std/bastring.h where both
find() and npos are defined

// This is from a subfunction actually, but it does the same
thing in main()
int main()
{
    string fred = "abcdefg"'
    int subIndex;

    subIndex = fred.find('-'); // since '-' does not occur in
fred, npos should be returned

   if (subIndex == npos)    //<< This is flagged "npos
undeclared"
        std::cout << "String not found\n"

    return(0);
}

I have a workaround, but I rather dislike workarounds.

Any ideas are appreciated.
