propagate change throughout.

2005-01-22 Christopher Faylor <cgf@timesys.com>
* pinfo.cc (pinfo::init): Move everything but the MapViewOfFileEx out
of the loop since trying multiple times to call CreateFileMapping

set_exit_state.

2005-01-15 Christopher Faylor <cgf@timesys.com>

for child, not for parent.
2005-01-13 Christopher Faylor <cgf@timesys.com>
* init.cc (dll_entry): Nuke attempt to set exit code since parent will
use windows exit code if needed.
* pinfo.cc (pinfo::exit): Move release() here to minimize pid creation
race (suggested by Pierre Humblet).
2005-01-12 Christopher Faylor <cgf@timesys.com>
Reorganize header file inclusion throughout so that cygerrno.h comes
