moving around unallocated HD space

I run a dual boot laptop with a 100GB hard drive. I have XP on one and Debian on the other.

My HD partitions look the following way:

1  NTFS ~43GB
2 Extended Partition (Linux Partitions)
        2a   /boot ~ 50MB
        2b   linux swap  ~1GB
        2c   /  ~ 35GB
and about 15 GB of unallocated space

This is the actual order from left to right if you were looking at the GParted window.

I'd like to move the unallocated space to a position just below the XP partition so that I can add it to the XP partition. I figured to do this I would have to move all the linux partition to the right such that the unallocated space was then before the linux partitions.

However, if I click move/resize on partition 2c, the slider bar doesn't have an arrow on the left side, just the right side, so I can increase this partition to fill the unallocated space, but not move it as one block of memory.

When I click on partition 2a or 2b both ends have arrows such that both ends can be changed.

Is there a way to accomplish what I want to do?

Thanks for any help,
