+\section{Architecture dependency}
+
+A problem which sometimes arises from writing multi-platform programs is that
+the basic C types are not defiend the same on all platforms. This holds true
+for both the length in bits of the standard types (such as int and long) as 
+well as their byte order, which might be little endian (typically
+on Intel computers) or big endian (typically on some Unix workstations). wxWindows
+defines types and macros that make it easy to write architecture independent
+code. The types are:
+
+wxInt32, wxInt16, wxInt8, wxUint32, wxUint16 = wxWord, wxUint8 = wxByte
+
+where wxInt32 stands for a 32-bit signed integer type etc. You can also check
+which architecture the program is compiled on using the wxBYTE\_ORDER define
+which is either wxBIG\_ENDIAN or wxLITTLE\_ENDIAN (in the future maybe wxPDP\_ENDIAN
+as well).
+
+The macros handling bit-swapping with respect to the applications endianness
+are described in the \helpref{Macros}{macros} section.
