I've managed to go upto the libstd++-v3 stage (make bootstrap with -O2) and
now I'm getting the following:

Going through mathconf.h, I get:
------------------------------------------------------------------
#ifdef isfinite
/* This is an ISO C99 function.  */
# define FINITE_P(X) isfinite (X)
# define FINITEF_P(X) isfinite (X)
# define FINITEL_P(X) isfinite (X)
#else
# ifdef IsNANorINF

   types.  */
#  define FINITE_P(X) (!IsNANorINF (X))
#  define FINITEF_P(X) (!IsNANorINF (X))
#  define FINITEL_P(X) (!IsNANorINF (X))
# else
#  if defined _GLIBCPP_HAVE_ISINF && defined _GLIBCPP_HAVE_ISNAN
#   define FINITE_P(X) ({ double __x = (X); !isinf (__x) && !isnan (__x); })
#  else
#   ifdef _GLIBCPP_HAVE_FINITE
#    define FINITE_P(X) finite (X)
#   else
#    error "We need FINITE_P"  <-- This is the error - Biswa
#   endif
#  endif
---------------------------------------

This is pretty strange because in /usr/include/nan.h, I have :
-----------------------------------------
#define IsNANorINF(X)  (((dnan *)&(X))->nan_parts.exponent == 0x7ff)
-----------------------------------------

So, obviously, IsNANorINF is defined. So the question is, why is it not
being detected ? Can anyone give me any clues ?

Janis, is this the same error as the one you are getting ?

Thanks.
Biswa.
