`which awk` is the wrong version of awk for $0.  It 
uses single precision. $0 requires a double-precision version of awk.
If worst comes to worst, you can get a double-precision version of awk by
going to the awk sources and changing AWKFLOAT from "float" to "double"
in the file awk.def, then recompiling all of awk.
