Summary: Installation procedure asks too much space

Initial Comment:
The installation procedure does not want to continue 
unless at least 270 megabyte is available. The installed 
package uses less than 190 MB. (Deleting the 
downloaded package frees up 35 MB afterwards.)
This concerns ghc-6-0-1.msi on Windows 98.

Oh well, as 1G now sets you back less than a dollar, 80Mb
isn't even pocket change ;-)

It's the installer runtime which does the global 'file costing'; 
exactly how it calculates its total isn't clear from the MSI SDK 
documentation. Who knows, perhaps it also includes the size 
of the uncompressed contents of the CAB (which all the files 
are compressed into at generation time) when computing its 
number? And, since this is for a Win9x box, the file system is 
probably VFAT, where file blocks are allocated in 8k chunks, 
leading to quite a bit of slop given how many files a GHC 
install tree contains. But, this is all just semi-educated 
guessing on my part.

Other than give precise numbers for the individual files (which 
the installer generator does), there's not much we can do.

I forgot to mention that I selected the typical installation 
.
