[Haskell-beginners] GHC-generated executables size

[.]

Hi,
I was playing around with ghc again, and I was wondering what makes
the executables so large and how I could make them smaller (strip works,
but is there anything more I can do?)
More specifically, I am compiling a program that uses the GTK+ bindings,
HDBC, and some things from Prelude.
The program simply displays a window, and reads and writes values
from/into a data base file. Not much, really.
Anyway, the program size is 20MB without stripping, and 10MB after
stripping ... 

Any hints?

Thanks and good night for now ..
Christian
