Dear Shin,

thanks for the report.  I believe your observation shows a bug
in Cygwin whereby a bogus version of std::floor(long double) is
provided.  You can verify this hypothesis using the C++ program

#include <cmath>
#include <cstdlib>

long double x = 13311002825915415087.0L;

int main() {
   long double y = std::floor(x);
   if (x != y)
     return 1;
   else
     return 0;
}

The program will return 1 if the version of Cygwin you are using
is affected (the one I am using is affected).

We have just uploaded a new snapshot of PPL 1.1 (to be released soon)
that works around this problem.  Can you please test it?
You can find the snapshot at

Please let us know how it goes.
Kind regards,

    Roberto
