We are using SLang and Samba, which both don't know about the "const" 
qualifier. The function is meant for exactly these cases, which I hope 
will disappear in the next future. But that's only a dream. :)

in vfs/samba/include/smb.h, line 72, you can find:

    int Debug1 (char *, ...);

in slang/include/slang.h, line 155:

    extern char *SLmemcpy (char *, char *, int);
