incompatibility between gawk and awka for match

I used the above version. But I think it should be the same as the main version for this issue. See below.

$ awk_code='BEGIN { print match("abc", /(a)/, a); print length(a), a[1]; for(k in a) print k, a[k] }'
$ awka "$awk_code" > "$tmpdir"/a.c
$ gcc -lawka -o "$tmpdir"/a.out "$tmpdir"/a.c
$ "$tmpdir"/a.out
