Dave (C-B),

Although apparently deviating from smbsh/Linux/glibc, I think the
following is related.

I have long suspected there is something with 64-bit stuff needing
attention.  Certainly under 2.0.7, and also, I'm 99% sure under earlier
versions and under the later 2.2.0alpha0, on a Sun U450 with Solaris 2.6
(32-bit mode) gives some warnings: 

   Compiling lib/system.c
   ../lib/system.c: In function `sys_readdir':
   ../lib/system.c:350: warning: return from incompatible pointer type

which is at the code:
   SMB_STRUCT_DIRENT *sys_readdir(DIR *dirp)
   {
   #if defined(HAVE_EXPLICIT_LARGEFILE_SUPPORT) && defined(HAVE_READDIR64)
     return readdir64(dirp);
   #else
     return readdir(dirp);
   #endif
   }

So I suspect there are some 64-bit declarations and some '#if ...' things
that perhaps need some laborious attention by someone who understands the
issues and understands the Samba declarations (and intentions behind the
declarations).

Hope that helps.
