When compiling PHP 4.0.n with Easysoft ODBC-ODBC Bridge 1.0.0.15, you may see compilation warnings about implicit conversion of integer to pointer. There are updated versions of the sqlext.h and sqltypes.h header files included with ODBC-ODBC Bridge that solve this issue. Upgrade the ODBC-ODBC Bridge client to 1.0.0.16 or above.
