Facing undefined symbols linker issue with Diab compiler when I type cast array of data from float to long long

Question

I wrote a small example code and executed in both GCC and DIAB compilers.

#include<stdio.h>
int main() 
{
    float a[10];

    long long int b[10];
    int i;
    for (i =0;i<10;i++)
    {
        a[i] = 1.256*i;
        b[i] = (long long int)a[i];
        printf("%f\t%lld\n",a[i],b[i]);
    }

    return 0;
}

The output in GCC compiler is:

0.000000 0 1.256000 1 2.512000 2 3.768000 3 5.024000 5 6.280000 6 7.536000 7 8.792000 8 10.048000 10 11.304000 11

The issue in DIAB compiler is :

dld.exe: warning: Undefined symbol '__asr64' in file 'sfpfftoll.o(C:\WINDRI~2\diab\580~1.0-3\PPCVLEES\libimpfp.a)' dld.exe: warning: Undefined symbol '__lsl64' in file 'sfpfftoll.o(C:\WINDRI~2\diab\580~1.0-3\PPCVLEES\libimpfp.a)' dld.exe: error: Undefined symbols found - no output written make.exe: *** [..\output\bin\xxxxxxx.elf] Error 1

Is there any work around to convert array of floats to array of long long int? I tried using pointers but still facing the same linker issue.
