go-curl does not compile on precise builders

[Dave Cheney]

Precise ships with Go version 1.0.0 (technically the tag is go1, but that is unhelpful)

This version of Go contains a bug in the cgo preprocessor which makes it incompatible with the go-curl library used by gwacl.

This bug is not present when compiling on Q and R which ship with a version of Go derived from go1.0.2

[Dave Cheney (dave-cheney)]

I have confirmed that this bug is present when compiling with Go versions up to 1.0.1. This bug was fixed when compiling with Go 1.0.2 or later.

[Julian Edwards (julian-edwards)]

We've remove go-curl as a dependency from gwacl now.

[Steve Langasek (vorlon)]

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
