GHCI and archive libraries.

[Keean Schupke]

Thaks guys... I realise it is a simple matter of unpacking the object 
files, however when using ghci for prototyping, it can be more 
convenient to have all the '.o's packed into a '.a'. As it is a simple 
matter to extract the .o files from the .a, I would have thought a 
fairly small change to the ghci code would have enabled using archive 
libraries. I think this change would aid usability. I don't know the 
ghci code at all, so it would take me a long time to make this change, 
as I would first have to understand the existing code. I was wondering 
if anyone familier with the ghci code could add archive library support? 
I suppose as a work around I could write a wrapper for ghci that 
extracts the .o files from the .a to a temp directory, and then calls 
ghci with the .o files on the command line.

    Regards,
    Keean.
