/**
 * @defgroup pj_dll_target Building Dynamic Link Libraries (DLL/DSO)
 * @ingroup pj_config
 * @{
 *
 * The libraries support generation of dynamic link libraries for
 * Symbian ABIv2 target (.dso/Dynamic Shared Object files, in Symbian
 * terms). Similar procedures may be applied for Win32 DLL with some 
 * modification.
 *
 * Depending on the platforms, these steps may be necessary in order to
 * produce the dynamic libraries:
 *  - Create the (Visual Studio) projects to produce DLL output. PJLIB
 *    does not provide ready to use project files to produce DLL, so
 *    you need to create these projects yourself. For Symbian, the MMP
 *    files have been setup to produce DSO files for targets that 
 *    require them.
 *  - In the (Visual Studio) projects, some macros need to be declared
 *    so that appropriate modifiers are added to symbol declarations
 *    and definitions. Please see the macro section below for information
 *    regarding these macros. For Symbian, these have been taken care by the
 *    MMP files.
 *  - Some build systems require .DEF file to be specified when creating
 *    the DLL. For Symbian, .DEF files are included in pjlib distribution,
 *    in <tt>pjlib/build.symbian</tt> directory. These DEF files are 
 *    created by running <tt>./makedef.sh all</tt> from this directory,
 *    inside Mingw.
 *
 * Macros related for building DLL/DSO files:
 *  - For platforms that supports dynamic link libraries generation,
 *    it must declare <tt>PJ_EXPORT_SPECIFIER</tt> macro which value contains
 *    the prefix to be added to symbol definition, to export this 
 *    symbol in the DLL/DSO. For example, on Win32/Visual Studio, the
 *    value of this macro is \a __declspec(dllexport), and for ARM 
 *    ABIv2/Symbian, the value is \a EXPORT_C. 
 *  - For platforms that supports linking with dynamic link libraries,
 *    it must declare <tt>PJ_IMPORT_SPECIFIER</tt> macro which value contains
 *    the prefix to be added to symbol declaration, to import this 
 *    symbol from a DLL/DSO. For example, on Win32/Visual Studio, the
 *    value of this macro is \a __declspec(dllimport), and for ARM 
 *    ABIv2/Symbian, the value is \a IMPORT_C. 
 *  - Both <tt>PJ_EXPORT_SPECIFIER</tt> and <tt>PJ_IMPORT_SPECIFIER</tt> 
 *    macros above can be declared in your \a config_site.h if they are not
 *    declared by pjlib.
 *  - When PJLIB is built as DLL/DSO, both <tt>PJ_DLL</tt> and 
 *    <tt>PJ_EXPORTING</tt> macros must be declared, so that 
 *     <tt>PJ_EXPORT_SPECIFIER</tt> modifier will be added into function
 *    definition.
 *  - When application wants to link dynamically with PJLIB, then it
 *    must declare <tt>PJ_DLL</tt> macro when using/including PJLIB header,
 *    so that <tt>PJ_IMPORT_SPECIFIER</tt> modifier is properly added into 
 *    symbol declarations.
 *
 * When <b>PJ_DLL</b> macro is not declared, static linking is assumed.
 *
 * For example, here are some settings to produce DLLs with Visual Studio
 * on Windows/Win32:
 *  - Create Visual Studio projects to produce DLL. Add the appropriate 
 *    project dependencies to avoid link errors.
 *  - In the projects, declare <tt>PJ_DLL</tt> and <tt>PJ_EXPORTING</tt> 
 *    macros.
 *  - Declare these macros in your <tt>config_site.h</tt>:
 \verbatim
        #define PJ_EXPORT_SPECIFIER  __declspec(dllexport)
        #define PJ_IMPORT_SPECIFIER  __declspec(dllimport)
 \endverbatim
 *  - And in the application (that links with the DLL) project, add 
 *    <tt>PJ_DLL</tt> in the macro declarations.
