mdbtools: [PATCH] Fixes in odbc.c to return size of returned strings and handle OLE data

[Even Rouault]

Package: mdbtools
Version: 0.5.99.0.6pre1.0.20051109-4
Severity: important

Attached a patch that fixes several issues in odbc.c that have been found
while using libmdbodbc.so with the OGR PGeo driver of the GDAL package.
- SQLDescribeCol doesn't return the string length in *pcbColName, which
  breaks CPLODBCStatement::CollectResultsInfo() in port/cpl_odbc.cpp in
  GDAL that uses that value to force a '\0' character at the end of the
  string
- SQLColAttributes doesn't return the string length in *pcbDesc, which
  breaks CPLODBCStatement::CollectResultsInfo() in port/cpl_odbc.cpp in
  GDAL that uses that value to force a '\0' character at the end of the
  string
- SQLGetData doesn't return the correct string length in *pcbValue. It
  should return strlen(rgbValue) instead of col->cur_value_len which is
  sometimes < strlen(rgbValue). That breaks CPLODBCStatement::Fetch in
  port/cpl_odbc.cpp that uses that value to force a '\0' character at
  the end of the string
- SQLGetData doesn't handle correctly OLE data type, which prevents the
  OGR PGeo driver from retrieving the geometry data
