Bug#211661: gcc-3.3: With -std=c99, the NAN and INFINITY macros are not regarded as constants

[Vincent Lefevre <vincent@vinc17.org>]

Package: gcc-3.3
Version: 1:3.3.2-0pre3
Severity: normal

When compiling the following program with gcc -std=c99

#include <math.h>
int main (void)
{
  static double x = NAN;
  return x == 0;
}

I get:

testconstnan.c: In function `main':
testconstnan.c:27: error: initializer element is not constant

But the ISO C standard says (7.12):

       [#5] The macro

               NAN

       is defined if and only if the implementation supports  quiet
       NaNs   for  the  float  type.   It  expands  to  a  constant
       expression of type float representing a quiet NaN.
