Failure with CGO

[LukeMauldin]

I have a package that compiles cleanly using go build that also uses CGO. One of my files (not one that has //+gen tag) has the line import C
When I run gen, I receive the error: commandline.go:7:8: could not import C (can't find import: )
gen should support packages that use CGO.

I'll have too look into this, having not used CGO myself.
