* backend: refactor dlhandle.h into oscompat.{cpp,h} Signed-off-by: Jared Van Bortel <jared@nomic.ai> * llmodel: alias std::filesystem Signed-off-by: Jared Van Bortel <jared@nomic.ai> * llmodel: use wide strings for paths on Windows Using the native path representation allows us to manipulate paths and call LoadLibraryEx without mangling non-ASCII characters. Signed-off-by: Jared Van Bortel <jared@nomic.ai> * llmodel: prefer built-in std::filesystem functionality Signed-off-by: Jared Van Bortel <jared@nomic.ai> * oscompat: fix string type error Signed-off-by: Jared Van Bortel <jared@nomic.ai> * backend: rename oscompat back to dlhandle Signed-off-by: Jared Van Bortel <jared@nomic.ai> * dlhandle: fix #includes Signed-off-by: Jared Van Bortel <jared@nomic.ai> * dlhandle: remove another #include Signed-off-by: Jared Van Bortel <jared@nomic.ai> * dlhandle: move dlhandle #include Signed-off-by: Jared Van Bortel <jared@nomic.ai> * dlhandle: remove #includes that are covered by dlhandle.h Signed-off-by: Jared Van Bortel <jared@nomic.ai> * llmodel: fix #include order Signed-off-by: Jared Van Bortel <jared@nomic.ai> --------- Signed-off-by: Jared Van Bortel <jared@nomic.ai>
