// The following block is the standard way of creating macros which make exporting
// from a DLL simpler. All files within this DLL are compiled with the Foundation_EXPORTS
// symbol defined on the command line. this symbol should not be defined on any project
// that uses this DLL. This way any other project whose source files include this file see
// Foundation_API functions as being imported from a DLL, whereas this DLL sees symbols
// defined with this macro as being exported.

// POCO_JOIN
//
// The following piece of macro magic joins the two
// arguments together, even when one of the arguments is
// itself a macro (see 16.3.1 in C++ standard).  The key
// is that macro expansion of macro arguments does not
// occur in POCO_DO_JOIN2 but does in POCO_DO_JOIN.
