- The cx_oracle "decimal detection" logic, which takes place

- The cx_oracle "decimal detection" logic, which takes place
for for result set columns with ambiguous numeric characteristics,
now uses the decimal point character determined by the locale/
NLS_LANG setting, using an on-first-connect detection of
this character.  cx_oracle 5.0.3 or greater is also required
when using a non-period-decimal-point NLS_LANG setting.
