--- Comment #38 from Stan markau0@lycos.com ---
As a rough test (forgetting my previous changes post) I added a rough unix to windows path convert to just after strcpyW( volumenameW, filename );
so that it looks like
strcpyW( volumenameW, filename );
WCHAR *p2;
/* Normalize path */ for (p2 = volumenameW; *p2; p2++) if (*p2 == '/') *p2 = '\';
With this the wine volume tests work and Native Access works.
