[Zope-DB] DCOracle2 on AIX5.2 -- issues

I have Python 2.4.2 installed on AIX 5.2.  With some trouble, I have been
able to compile and install dco2.so.  The main problem was that the header
files desired by setup.py were not found in oracle_home, but elsewhere in
my Oracle installation -- they appear to be part of Oracle 8, not Oracle 9,
at least here at AEP.  oci.h was not found in oracle_9_home/rdbms/public,
but in oracle_8_home/rdbms/demos.  nzt.h and ociextp.h were not found in
oracle_9_home/rdbms/public, but in oracle_8_home/rdbms/public.  There
exists no oracle_9_home/lib/libclntsh.so here, but instead,

At any rate, the installed "worked," insofar as dco2.so was compiled and
installed in .../site-packages. I have been able to import dco2 without
complaint from python.  I have not tried to use it yet.

However, during compilation of cdo2.o, I did encounter these symptoms:

cc_r -DNDEBUG -O -I/oracle/product/
-I/oracle/product/ -I/oracle/product/
/plsql/public -I/oracle/product/
-I/oracle/product/ -I/oracle/product/
-I/app/sandbox/s625662/installed/include/python2.4 -c src/dco2.c -o
build/temp.aix-5.2-2.4/src/dco2.o -brtl -bexpall -DORACLE8i
"src/dco2.c", line 5004.38: 1506-280 (W) Function argument assignment
between types "unsigned long*" and "long*" is not allowed.
"src/dco2.c", line 6066.25: 1506-068 (W) Operation between types "short*"
and "unsigned short*" is not allowed.
"src/dco2.c", line 6109.25: 1506-068 (W) Operation between types "short*"
and "unsigned short*" is not allowed.

If anyone could suggest a possible way to correct these problems, I would
appreciate it.  Note that the compiler is NOT gcc, but AIX's native xlc,
here called with "cc_r."  This was the same compiler that we used to build
Python itself -- without encountering any such complaints.

Also I would appreciate anyone's comment on the significance lack of
correspondence between the file structure expected by setup.py and that in
my Oracle home.
