/* ??? This file has been modified to work with newlib's way of storing
|
|
`errno'. Arguably there's no need and arguably we shouldn't diverge
|
|
from go32 sources. If you feel strongly about it, please change it.
|
|
The interface between newlib and system's version of errno is via
|
|
__errno, so there's no problem in storing errno in a different place
|
|
(any changes can be dealt with inside __errno). */
