+ <listitem><para>Select a target-specific I/O package. The choices are 'stdio'
+ which is a generic abstraction using POSIX file I/O APIs
+ (<function>read</function>, <function>write</function>,
+ <function>lseek</function>, etc.), and 'stdio_pure' which is similar
+ but only uses standard C file I/O APIs (<function>fread</function>,
+ <function>fwrite</function>, <function>fseek</function>, etc.).
+ The 'stdio_posix' choice is a synonym for 'stdio'.
+ The default is 'stdio'. This option can change the library ABI.
