* os_win32.h: new file, providing a public and portable interface
|
||||
to the SHGetFolderPath function for older flavours of Windows.
|
||||
* os_win32.C: tighten up code. Define the ShGetFolder class. Make
|
||||
use of Microsoft's NewAPIs.h if available to provide us with
|
||||
runtime support for Windows 95.
|
||||
(internal_path): always pass the path through GetLongPathName.
|
||||
|
||||
* package.C.in: move lots of stuff out and into os_win32.C.
