GHC Task Ticket # 601 suggests replacing GMP with OpenSSL's Bignum

From the ticket, this looks very scary:

But in this case, yes, you can't. You need to provide way to
relink gmp in you program. As far as I know, this is simply possible
by taking all the objs --make generates, other objs and libs and
giving them on - users need to have ghc distro+their own gmp set in.
Hi Esa -
Thanks for reminding me about the distinction between source and object
files. I keep forgetting that object files exist (!) and that it's
sufficient for LGPL to just make them available.
Still, a slight problem is that since there is one object file per source
file, the names of the object files give quite a lot of information away
about the structure of the program especially when they are arranged in a
module hierarchy, so I'll be glad when GMP is replaced by something without
such a burdensome licence. (Although perhaps I can bundle my object files
into a single library file but I don't know how to do this yet, or if it
would really help in the goal to make the code completely obfuscated,
impenetrable, and unavailable to any rival company... ;-) )
Thanks again,
Brian.
