* file.c (move_dir_dir): Give an error when an attempt is made to move an empty directory into itself. 1999-06-14 Wayne Roberts <wroberts1@cx983858-b.orng1.occa.home.com> * vfs/smbfs.c: New file. Implements the Samba-based file system. * vfs/vfs.h: Declare vfs_smbfs_ops, vfs_file_is_smb. * vfs/vfs.c (vfs_file_is_smb): implemented. (vfs_init) register smbfs. * vfs/samba: Incorporate SAMBA source code required for smbfs 1999-05-27 Miguel de Icaza <miguel@nuclecu.unam.mx> * Make.common.in (confdir): Define confdir as sysconfdir. This should fix the problem we had with FSSTND distributions.

/* this tests whether getgroups actually returns lists of integers
|
|
rather than gid_t. The test only works if the user running
|
|
the test is in at least 1 group
|

The test is designed to check for those broken OSes that define
|
|
getgroups() as returning an array of gid_t but actually return a
|
|
array of ints! Ultrix is one culprit
