The gawk doc includes an awk implementatin of strtonum that can
be used with other awks, so the above isn't an issue.

No.

This is accidental, since those versions just call strtod and GLIBC
strtod handles hex values.  This is discussed somewhat in the gawk
doc.  The upshot is that you cannot rely on that behavior on non-GLIBC
systems.
