Question about cffi-libffi on win32

[Rujia Liu]

Dear all,

I'm using SBCL 1.1.4.0.mswin.1288-90ab477. I want to use cffi-libffi but
failed. Here is what I did:

1. First, download libffi_3.0.6-1_win32.zip from
http://ftp.gnome.org/pub/GNOME/binaries/win32/dependencies/ and drop
libff-5.dll to a place that SBCL can find.
2. use quicklisp to load the cffi-libffi system. However, I got the
following error:

* (ql:quickload "cffi-libffi")
To load "cffi-libffi":
  Load 1 ASDF system:

note: SBCL on windows can't redirect output.

I noticed that .....\cffi_0.11.2\libffi\libffi-win32.c does NOT exist, even
in git repository.
What should I do now?

BTW: How to change gcc's location? I used grep in cffi's directory but
can't find it.
My MinGW was installed somewhere else, I had to copy it to c:/msys/1.0/bin
so that cffi-libffi can find it (I saw a "can't fork" error message before
doing so).

Thanks in advance.
