 @cindex GCC and portability
 
-The main goal of GCC was to make a good, fast compiler for machines in
-the class that the GNU system aims to run on: 32-bit machines that address
-8-bit bytes and have several general registers.  Elegance, theoretical
-power and simplicity are only secondary.
+GCC itself aims to be portable to any machine where @code{int} is at least
+a 32-bit type.  It aims to target machines with a flat (non-segmented) byte
+addressed data address space (the code address space can be separate).
+Target ABIs may have 8, 16, 32 or 64-bit @code{int} type. @code{char}
+can be wider than 8 bits.
 
 GCC gets most of the information about the target machine from a machine
 description which gives an algebraic formula for each of the machine's
