Thanks for posting. Would love to see a project like this slowly work its way towards full compatibility, it will be a long road though. There are so many useful projects written in c that would be safer and easier to extend for Go programmers if written in Go. I'm sure a lot of people would love to embed SQLite without using cgo. This also removes a big barrier to porting older libraries which is likely to be the first use case.
Even if the Go produced is not the best (as the Go team found with their compiler) if it runs and the output is the same it could then be used by Go programs and tidied up later.
