[cffi-devel] Fix CFFI-UFFI-compat on ECL

[Michael Raskin]

	Hello.

	I am trying to simplify ASDF-Install'ing Cells-GTK on different
platforms. When trying with ECL, I find the following problem: CFFI
defines uffi-compat package with "uffi" alias. Comment even expresses
doubt whether it is a good idea. ECL has its own UFFI. So CFFI should
either not declare such nickname for ECL or remove the alias from "FFI"
package. I think the second is a better (although marginally more
complex) behavior, because it increases portability and reduces number
of people who notice implementation quirks of UFFI package.

	I include sample patch to remove this alias. I hope something like that
will get into the next release..

	Thanks
Michael Raskin
