That's probably the size of the C library on your machine. The only
difference between a static bash and a `normal' bash is that the system
libraries are linked in instead of being dynamically linked at run time.
I built a minimal bash (--enable-minimal-config) on my machine (Mac OS X,
where static linking isn't possible), and it ended up being about half
as big as a bash-4.2.20 build. I had to fix a few things to do it.
