/*
 * This header provides a macro to handle correct symbol imports/exports
 * on platforms that require explicit instructions to make symbols public,
 * or differentiate between exported and imported symbols.
 * 
 * Win32 compilers use this information, and gcc4 can use it on *nix
 * to reduce the size of the export symbol table and get faster runtime
 * linking.
 *
 * All declarations of public API should be marked with the PODOFO_API macro.
 * Separate definitions need not be annotated, even in headers.
 *
 * Usage examples:
 *
 * class PODOFO_API PdfArray : public PdfDataContainer {
 *     ...
 * };
 *
 * bool PODOFO_API doThatThing();
