website: inconsistency in supported OS X versions

[0xmohit]

https://golang.org/dl/ mentions:

Apple OS X
OS X 10.8 or later, Intel 64-bit processor

https://golang.org/doc/install says:

Official binary distributions are available for ...
Mac OS X (10.7 and above)

[bradfitz]

And later down the page, it says the requirements for compiling from source are "Mac OS X 10.7 or later".

I seem to recall that 10.7 is the minimum requirement for building for source, but somehow the binaries we produce (or the packaging) requires 10.8. I forget the details. @adg?

But the first mistake you cited is easy to fix at least.

I kept this bug open (using "Updates" in the commit message) so we can figure out what the story with source vs binary release supported versions is on OS X. I was waiting for @adg.

Okay, I'll tag this for 1.7 then, hopefully we can get the docs right before we release.

[adg]

I don't remember anymore.
I guess we'll have to test it to make sure.

I'll try a build on OS X 10.7 and see what happens.

Just tried OS X 10.7. It doesn't even compile:

crypto/x509
# crypto/x509
crypto/x509/root_cgo_darwin.go: In function 'FetchPEMRoots':
crypto/x509/root_cgo_darwin.go:97: error: 'for' loop initial declaration used outside C99 mode
crypto/x509/root_cgo_darwin.go:106: error: 'for' loop initial declaration used outside C99 mode

encoding

I'm sure we can work around it, but there's no point. And we don't want to run builders for OS X 10.{7,8,9,10,11,12}. Too many. 8 is old enough. Plus I still recall that 7 (Lion) leaked pipes in exec or something.

I'll fix the docs.
