fscanf "%lf" misses the "-" sign in "-5.0e+00" on cygwin 1.5.13-1


Hi,
I'm using cygwin 1.5.13-1 and gcc version 3.3.3 to compile the following foo.C :


#include <stdio.h>
#include <stdlib.h>
int main()
{
 FILE *ff = fopen( "foo.dat", "r");
 double x;
 int n = fscanf( ff, "%lf", &x);
 printf( "n=%d x=%lf\n", n, x);
 fclose(ff);
 return 0;
}

foo.dat contains the single text line:

-5.0e+00

The compiler does'nt show any warning and when executed prints:

n=1 x=5.000000

missing the "-" sign.

As soon as you replace the line in foo.dat by "-5.0e+01", thing works better and the sign shows up.
When you run the executable on cygwin 1.5.12-1 it works fine.
Am I doing something wrong or is this a bug in some new dlls within cygwin 1.5.13-1 ?
Thank you for any hint/help
