Supporting all gawk functions

[prRZ5F4LXZ]

It seems that some gawk functions are not supported by awka. Could those functions be supported?

$ awk 'BEGIN { x=x; print typeof(x) }'
unassigned
$ awka 'BEGIN { x=x; print typeof(x) }' > a.c
$ gcc -lawka a.c
a.c:16:44: error: implicit declaration of function 'typeof_fn' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
  awka_print(NULL, 0, 0, awka_arg1(a_TEMP, typeof_fn(awka_arg1(a_TEMP, x_awk))));
                                           ^

typeof() and isarry() added in #12

typeof() is still not fully compatible. See below.

main.sh> awk_code='BEGIN { x=x; print typeof(x) }'
main.sh> awka "$awk_code" > "$tmpdir"/a.c
main.sh> gcc -lawka -o "$tmpdir"/a.out "$tmpdir"/a.c
main.sh> gawk "$awk_code"
unassigned
main.sh> "$tmpdir"/a.out
untyped
