gpm related crash fix

[Dmitry Alexeyev <dmi_a qnx org ru>]

Hello! 

Some days ago I put my linux in pretty weird state, similar to single 
user mode. In this mode gpmd dies.. 
The error was in some rc.d level 6 script, which didn't handle `reboot' 
properly, so returned to login prompt (single user). 

When I tried to run mc, it crashed. gdb said gpm_fd was -2, and mc only 
checks for -1. 

Attached key.c.diff changes checking for == -1 to  < 0, which is more 
general case. 

view.c.diff fixes warning. 

WBR,
Dmitry
