[ about ar and symbol table ]

The difference is from the change of the encoding of filename.

Then, we have some alternatives.
1. ar produces Berkeley file format
2. ar produces SysV ("/" at the end of file names) file format
ar symbol table:
a. ar doesn't produce symbol table
b. ar produces "/" table
c. ar produces "__.SYMDEF" table
A. ranlib produces "__.SYMDEF" table
B. ranlib produces "/" table
C. ranlib produces "__.SYMDEF" table unless it has "/" table
D. ranlib produces "/" table unless it has "__.SYMDEF" table
E. ranlib doesn't exist
The orignal Berkeley systems are 1-a-A.
The SysV systems are 2-b-E.
Currently we have 1-b-C toolchain.
Apparently, 1-b-* and 2-c-* are inconsistent in the sense
of namespace of filename of the archived files.
My proposal was 1-a-A or 1-a-C, which is compatible to Berkeley's.

Then, is your proposal is 2-b-E, just like as SysV systems?
Changing archive format will make compatibility problems...
