[Nut-upsdev] gcc4 compiler warnings

[Niklas Edmundsson]

Hi all!

The following files emits warnings when compiled with gcc 4.0:
al175.c
bcmxcp_ser.c
belkinunv.c
cyberpower.c
everups.c
powercom.c
solis.c

All warnings seem to be of this variety:
everups.c:38: warning: pointer targets in passing argument 2 of 'ser_get_char' differ in signedness

I suggest that those who fiddles with those drivers fixes the warnings 
and verifies that it works afterwards. I can provide the complete 
buildlog if there's anyone that doesn't have access to a gcc4-equipped 
machine.

/Nikke - prefers a noise free build output :)
