SAMBA 2.0.7. - mangled names problems

[Ludek Babor]

Hello,
after upgrade Samba from 1.9.17p4 to 2.0.7. I have problems with name 
mangling.

In one directory I have these files (only):
0011_BAR_ISSUEAGRES.CSV
0011_MIR_STKGEN.CSV
0011_OLO_ISSUEMPSPEC.CSV
0011_RET_ISSUEAGRES.CSV

When I look at these files (DIR /X) from Windows95 or WindowsNT 
Workstation 4.0 clients I can see this:
0011_~%Y.CSV    0011_BAR_ISSUEAGRES.CSV
0011_~$%.CSV    0011_MIR_STKGEN.CSV
0011_~%L.CSV    0011_OLO_ISSUEMPSPEC.CSV
0011_~%Y.CSV    0011_RET_ISSUEAGRES.CSV

First problem:
The same short name 0011_~%Y.CSV is for different long names 
(0011_RET_ISSUEAGRES.CSV and 0011_BAR_ISSUEAGRES.CSV).
