Re: FW: ghc, linux

I installed a very old version of GHC in the same laptop in 2001 and it was 
working well ("no matter how big the program was"). Now, I upgraded it to 
version 6.2.2, but it becomes very slow and asks more Memory or Space.

I know, 64M memory is not big at all nowadays, but I don't think GHC should 
ask more than that and force me to throw away my old laptop -:). In fact, 
most of my work can be done within 64M except GHC.
