ake it a global variable, to guard against dead code elimination.
Oops, the configure script compiling with -O2 optimization. The
compilation of the following code still suceesss.
#include
int a;
int
main ()
{
float f = 0.0;
a = isinf (f);
return 0;
}
Do I misunderstand? Since I am the newbie of C, I consulted this page:

Yes, I contact rrdtool maintainer. Thank you.

't
have isinf().
/* Solaris */
#if (! defined(HAVE_ISINF) && defined(HAVE_FPCLASS))
# define HAVE_ISINF 1
# define isinf(a) (fpclass(a) == FP_NINF || fpclass(a) == FP_PINF)
#endif
Is this gcc's problem? Or should I contact rrdtool's developer?
Regards.
