/*
* Please check the following before installing this file:
*
* Make sure USG is #defined if you are on a USG system!
*
* Check the value of _NFILE against the one in your /usr/include/stdio.h.
* (USG only)
*
* Check whether your libc.a sprintf function returns
* an int (as do most) versus a char* (BSD), and (un)comment
* the corresponding SPRINTF_RETURNS_INT line.
*
* Check the value of BUFSIZ against the one in your /usr/include/stdio.h.
*
* Carefully check the fields and order of _iobuf declaration against
* the one in your /usr/include/stdio.h. Xenix-based systems
* may need some re-ordering of _iobuf. fields.
*
* Note that some _IOXXX #defines may not be present in your
* /usr/include/stdio.h. This is ok, so long as the ones that
* are present in both are set to the same values.
*
* Some of the prototypes refer to functions that may not be
* present in your libc.a. This is ok so long as you do not
* actually call such functions.
