Description:
When compiling the Connector/C++ source, the compiler returns an error.

'snprintf' was not declared in this scope or
'printf' was not declared in this scope 
 
The is because on some OS distributions stdio is not included by default. 

The source was obtained from http://dev.mysql.com/downloads/connector/cpp/1.0.html

How to repeat:
It should be easy to repeat by compiling on Ubuntu or Fedora.

Suggested fix:
Add the line '#include <cstdio> to at least the following files and any other files that use printf/snprintf or related functions.

driver/mysql_resultbind.cpp
driver/mysql_art_resultset.cpp
test/unit/classes/resultsetmetadata.cpp
test/unit/unit_fixture.cpp
