While doing a quick test of the novice win32 example from http://wiki.github.com/ffi/ffi/windows-examples across jruby and mri 1.8 and 1.9, using

ffi_lib :kernel32

works as expected on 1.9 and fails on 1.8 due to 1.8's "File.basename" used in "map_library_name" on line 61 of

http://github.com/ffi/ffi/blob/master/lib/ffi/ffi.rb

not accepting Symbol's.

I've updated my examples on the wiki to use only String's, but am wondering if FFI core should be agnostic for the ffi_lib arg?

I personally prefer the Symbol style but I don't really have strong feelings other than "keep lib loads fast."
