So I do see one difference in behavior between your patch and mine,
and that's on a Solaris 8 32-bit sparc platform.  Using the test
case:

    gawk --lint 'BEGIN { x=2**60; for(i=60;i<=65;i++) { printf "2^%d= %s %d 
%g\n",i,x,x,x; x*=2}}'

the output from your patch and mine differs as follows:

< gawk: warning: [s]printf: value 1.84467e+19 is out of range for `%d' format
< 2^64= 1.84467e+19 1.84467e+19 1.84467e+19
---
> 2^64= 1.84467e+19 18446744073709551615 1.84467e+19

I guess your patch is more correct, although neither one gives the user
exactly what he was asking for (a proper %d result; my patch is off by 1,
whereas yours gives a warning and prints %g format instead).
