GCC 4.4 cross compiler and issue with __floatdidf

["Vincent R." <forumer@xxxxxxxxxxxxxxx>]

Hi,

When compiling the following code with a gcc 4.4 cross-compiler targetting
arm wince platform I get a problem with undefined reference __floatdidf :

find__floatdidf.c:
----

#include <windows.h>

LONGLONG _evil_time_freq;
LONGLONG _evil_time_count;
long     _evil_time_second;

double
evil_time_get()
{
  LARGE_INTEGER count;

  QueryPerformanceCounter(&count);

  return (double)_evil_time_second + (double)(count.QuadPart -
                          _evil_time_count)/
                          (double)_evil_time_freq;
}

//int main(int argc, char* argv[])
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR lpCmdLine,
int nCmdShow)
{
  double dTime = evil_time_get();
  printf("ret : %d\n", dTime);

  return 0;
}

Any idea ?
