[Python-checkins] python/dist/src/Modules posixmodule.c,2.295,2.296

[aimacintyre@users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Modules
In directory sc8-pr-cvs1:/tmp/cvs-serv20011

Modified Files:
	posixmodule.c 
Log Message:
- DosSetExtLIBPATH objects to a NULL pointer, but a pointer to a NULL 
  string does what is expected (ie unset [BEGIN|END]LIBPATH)

- set the size of the DosQuerySysInfo buffer correctly; it was safe, 
  but incorrect (allowing a 1 element overrun)
