1.1.0: wrong negative HUGE_VAL

Hi,

yesterday I installed cygwin using setup and internet download from
ftp.sunet.se. Unfortunately my programs developed under B20 don't run anymore
properly.
     The problem is that HUGE_VAL contains the wrong negative value
-6.59614e-229. The following test program reproduces my probelm:

#include <math.h>
#include <stdio.h>

int main()
{
  printf("HUGE_VAL is: %g\n", HUGE_VAL);
  printf(" 1.0/0.0 is: %g\n", 1.0/0.0);
}

Compiled under 1.1.0, the program produces (using gcc or g++):
HUGE_VAL is: -6.59614e-229
 1.0/0.0 is: Inf

Compiled under B20, it produces the same output when using gcc, but with g++ the
 result is as expected:
HUGE_VAL is: Inf
 1.0/0.0 is: Inf

Can you help?

P.S. here is the output of cygcheck:
