Re: gawk number to string bug

[Andrew J. Schorr]

Oops, the last patch used the isfinite() function, but that should
probably be avoided, since it doesn't seem to be present on some
platforms (e.g. it's not in Solaris 8).  Revised patch attached.

$ ./gawk --lint 'BEGIN {x = log(0); printf "x = %s %g %d %x\n",x,x,x,x}'
gawk: warning: [s]printf: value -inf is out of range for `%d' format
gawk: warning: [s]printf: value -inf is out of range for `%x' format
x = -inf -inf -inf -inf

$ ./gawk --lint 'BEGIN {x = sqrt(-1); printf "x = %s %g %d %x\n",x,x,x,x}'
gawk: warning: sqrt: called with negative argument -1
gawk: warning: [s]printf: value nan is out of range for `%d' format
gawk: warning: [s]printf: value nan is out of range for `%x' format
x = nan nan nan nan

I suspect we should add some test cases for these various formatting issues...

Andy
