Couldn't load foreing library "clsql_uffi" drives me mad

Hi everyone,

that problem arose from time to time and consumed half a day without any
step further:

On my Linux box, everything is okay with clsql. On Windows it is not. I
once had a running environment but after switching to some newer
versions of my libraries it is broken again:

I have Windows XP virtual machine with CCL 1.7-dev-r14645M-trunk
(Windows X8632). I use quicklisp from scratch. I (ql:quickload "clsql")
then I did a

(require 'clsql)
(require 'clsql-sqlite3)

and as so often it broke with

Couldn't load foreign library "clsql_uffi". (searched
CLSQL-SYS:*FOREIGN-LIBRARY-SEARCH-PATHS*).


I searched the web and tried to find my own solution that worked
beforehand but I didn't get clsql running. Is there anything I am doing
wrong? Or a recipe on how to get clsql running on windows? The problem
arose that often that I hope for a general solution. Perhaps we can put
it in the documentation.

Kind regards, Daniel
