Hi,
I'm trying to use STL container "map" with MySQL server but I'm getting the following link error at the very end.


CXXFLAGS="-DUSE_SYS_STL"

table.h has the following

#include <map> 
.
.
.
std::map<int,int> foo;


Are there any name conflicts, since table.h is eventually included in just about every source ?
I'm not sure if I can use namespace to work around this problem ?

Thanks,
Hiromichi
