Can't get mkfs.ext3 on Busybox 1.20.2

Hope this is the right forum for a Busybox question.

I'm trying to get the mke2fs (mkfs.ext3) utility compiled into busybox using menuconfig. The menu only gives the ext2 option, no ext3. I remember reading somewhere that if you give the -j option, it will include journalling and essentially be an ext3 partition tool. However, even using that option the partition is still being configured as ext2.
I checked the busybox-1.20.2/e2fsprogs/Config.src file and it has the relevant option commented out.

### config MKE2FS
### bool "mke2fs"
### default y
### help
### mke2fs is used to create an ext2/ext3 filesystem. The normal compat
### symlinks 'mkfs.ext2' and 'mkfs.ext3' are also provided.

What can I do to enable mkfs.ext3? Can I just manually remove the # comments? I don't want to mess up the build. I don't see any other place in menuconfig to enable ext3.

Did you check tune2fs? (You should have CONFIG_MKFS_EXT2=y and CONFIG_TUNE2FS=y in your .config file -or whatever configuration file you're using.)
(I don't have BusyBox installed right now, so I couldn't check.)

Thanks for the suggestion, I added those tools to busybox, but they don't seem to have ext3 support for mkfs. I've just had to remove mke2fs from busybox and use e2fsprogs package separately. I just find it odd busybox didn't support it in the .config.
