I can't explain this one, how would fromRational
know that it has to create a Double ?

are there any difference with 4.06 and 4.08 ?
Below is a list of fixes to get FranTk working with ghc4.08.

Run configure like normal, i.e.:
./configure
I implemented the programs for hash1 and hash2, but I had to
make a lot of changes to FiniteMap to get them to work:
- I changed foldl to foldl' (as defined in Hugs).
- I made foldFM strict (like foldl').
- I made the datatype FiniteMap strict (put !'s everywhere).
I put the programs below,

Hi,
I noticed ghc (version 4.08.1) floating point performance is
really slow on my computer: a 270Mhz sun ultra5. The program
below does 1 milion floating point multiplications and takes
2 seconds to run. I made a profile and it says most of the
time (93%) is spent in the function bar. Any idea

Hi,
I'm trying to write an interface for a C library that
uses a Boehm type garbage collector. So, I need to get
the address of the bottom of the C stack. In a C
application this would look something like:
main()
{
int bottomOfStack;
}
Where "bottomOfStack" would be the thing I need.
