[cffi-devel] Possible bug reading *FOREIGN-LIBRARY-DIRECTORIES* on Windows 7

[Ralph Möritz]

I've observed what appears to be a bug on Windows using CCL 1.8 & the
latest CFFI version from Quicklisp (0.10.7.1).

It seems *FOREIGN-LIBRARY-DIRECTORIES* is not being read
correctly. I've placed `sqlite3.dll` in
`C:\users\ralphm\temp\lib`. Below are the results of evaluating
`(cffi:load-foreign-library '(:default "sqlite3"))` for different
values of *FOREIGN-LIBRARY-DIRECTORIES*. It appears the trailing `/`
is required but I haven't seen this documented in the manual - is this
intended behaviour?

'("c:/users/ralphm/temp/lib/") 
==> #<FOREIGN-LIBRARY DEFAULT-3009 "sqlite3.dll">

'(#p"c:/users/ralphm/temp/lib/") 
==> #<FOREIGN-LIBRARY DEFAULT-3009 "sqlite3.dll">

'("c:/users/ralphm/temp/lib") 
==> Unable to load foreign library (DEFAULT-3009).  
    Error opening shared library sqlite3.dll : The specified module 
    could not be found. .

'(#p"c:/users/ralphm/temp/lib") 
==> Unable to load foreign library (DEFAULT-3009).
    Error opening shared library sqlite3.dll : The specified module 
    could not be found. .

Cheers,
