PL48: statfs, PatchLev.h

[Christian_Felsch@hh.maus.de (Christian Felsch)]

 Hi again!

1. I think one of the two PatchLev.h should be removed! The one in lib/ set 
   PatchLevel to 47 and the one in include/ to 48!?
   I meen PatchLev.h should only be in the lib sources and do not installed 
   with the other include files.

2. Have I found a bug in statfs()?
   If I try to get infos about "U:\j" (ZIP drive without a medium), I got 
   wrong values in the struct statfs.
   Take a look at statfs():
   
     ...
     r = stat(path, &statbuf);
     if (r == -1)
        return -1;

     ...
     Dfree(&free, statbuf.st_dev + 1);

   The first stat() works correct because U:\j is valid drive/path. But then 
   the Dfree() returns -1 because no informations about the medium are 
   available. In this case I think the return value of Dfree() had to be 
   checked. My propose:
