gawk number to string bug

I ran into a bug in how gawk converts numbers into strings.  

Running the program
  BEGIN { print 9223372036854775808 }
on a 64-bit machine.  On a 32-bit machine, the same program prints out
which is correct.

Note that 9223372036854775808 == 2^63.  Printing out other powers of 2
is OK.

Version details:
  gawk version 3.1.5, freshly downloaded from gnu.org
  gcc (GCC) 3.4.4 (Gentoo 3.4.4-r1, ssp-3.4.4-1.0, pie-8.7.8)
  uname -a output:
    Linux pixie 2.6.12-gentoo-r10 #2 SMP Tue Nov 1 03:42:22 PST 2005
    x86_64 Dual Core AMD Opteron(tm) Processor 275 AuthenticAMD GNU/Linux

(the 32-bit example used gawk version 3.1.3)
