00002  * This header file exists because getting iosh.cc to compile under
00003  * many different combinations of versions of gcc/libc/kernel is very difficult.
00004  * This defines the interface that iosh.cc can always use and hopefully allow
00005  * us to isolate the version problems in cppio.c.
