update netcat 1.11 to 1.12

update netcat 1.11 to 1.12

why?

nc -lp port (remote )
nc ip port -e cmd.exe (local)
after ctrl+c cmd.exe no exit,socket no shutdown,remote's nc no exit!
it is a bug!so write netcat 1.12.
only modify doexec.c

Netcat 1.12 for NT
UPDATE 04/20/2013 by chenghao0511@gmail.com [ctrl+c]

how to update:in doexec.c
