The go/build package already recognizes
system-specific file names like
mycode_darwin.go
mycode_darwin_386.go
mycode_386.s
However, it is also common to write files that
apply to multiple architectures, so a recent CL added
to go/build the ability to process comments
listing a set of conditions for building. For example:
// +build darwin freebsd openbsd/386
says that this file should be compiled only on
OS X, FreeBSD, or 32-bit x86 OpenBSD systems.
These conventions are not yet documented
(hence this long CL description).
This CL adds build comments to the multi-system
files in the core library, a step toward making it
possible to use go/build to build them.
With this change go/build can handle crypto/rand,
exec, net, path/filepath, os/user, and time.
os and syscall need additional adjustments.

Drop laddr argument from Dial.
Drop cname return from LookupHost.
Add LookupIP, LookupCNAME, ParseCIDR, IP.Equal.
Export SplitHostPort, JoinHostPort.
Add AAAA (IPv6) support to host lookups.
Preparations for implementing some of the
lookups using cgo.
ParseCIDR and IP.Equal are logically new in this CL
but accidentally snuck into an earlier CL about unused
labels that was in the same client.
In crypto/tls, drop laddr from Dial to match net.

parsing and printing to new syntax.
Use -oldparser to parse the old syntax,
use -oldprinter to print the old syntax.
2) Change default gofmt formatting settings
to use tabs for indentation only and to use
spaces for alignment. This will make the code
alignment insensitive to an editor's tabwidth.
Use -spaces=false to use tabs for alignment.
3) Manually changed src/exp/parser/parser_test.go
so that it doesn't try to parse the parser's
source files using the old syntax (they have
new syntax now).
4) gofmt -w src misc test/bench
3rd set of files.

echo back context of call in error if likely to be useful.
For example, if os.Open("/etc/passwd", os.O_RDONLY)
fails with syscall.EPERM, it returns as the os.Error
&PathError{
Op: "open",
Path: "/etc/passwd"
Error: os.EPERM
}
which formats as
open /etc/passwd: permission denied
