Cannot compile freebsd-base-graphics (4c5467a) on FreeBSD 10.2, compiler fails to recognize warning option

[Arto Pekkanen]

Hmmm. I'll RTFM on Git and see if I can check out 4c5467 while waiting 
for merge from/to HEAD.

Is the commit that should still work this: 
https://github.com/freebsd/freebsd-base-graphics/commit/4c5467a1f6fed8e7b7078de23e920a6d55712188
??

Were there any important commit bits after 4c5467 that would change how 
the driver functions?
