A casualty of https://golang.org/cl/10195044.
If x is an 32-bit int and u is a 64-bit ulong,
u = (uint)x // converts to uint before extension, so zero fills
u = (ulong)x // sign-extends

Built after adding -Wconversion to the list of compiler
arguments used when building. I believe these are all OK
assuming we will not change the API. There is no effort to
detect overflow due to very long strings.

Before, an empty TMPDIR would lead to:

Change build system to set GO_EXTLINK_ENABLED=0 by default for
OS X 10.6, since the system linker has a bug and can not
handle the object files generated by 6l.
Fixes#5130.

lib9: fix runcmd, removeall, and tempdir functions
cmd/dist: Include run_plan9.c and tempdir_plan9.c
from lib9 for build, and in general consider
file names containing "plan9" for building.
cmd/ld: provide function args for the new functions
from lib9.

The Plan 9 compilers complain about not
having type information for the function,
which sets off type signature problems
during the linking stage.

This CL adds a flag parser that matches the semantics of Go's
package flag. It also changes the linkers and compilers to use
the new flag parser.
Command lines that used to work, like
8c -FVw
6c -Dfoo
5g -I/foo/bar
now need to be split into separate arguments:
8c -F -V -w
6c -D foo
5g -I /foo/bar
The new spacing will work with both old and new tools.
The new parser also allows = for arguments, as in
6c -D=foo
5g -I=/foo/bar
but that syntax will not work with the old tools.
In addition to matching standard Go binary flag parsing,
the new flag parser generates more detailed usage messages
and opens the door to long flag names.
The recently added gc flag -= has been renamed -complete.

A new environment variable GO386 is introduced to choose between
code generation targeting 387 or SSE2. No auto-detection is
performed and the setting defaults to 387 to preserve previous
behaviour.
The patch is a reorganization of CL6549052 by rsc.
Fixes#3912.

This is required by the spec to produce the replacement char.
The fix lies in lib9's rune code.

it actually uses p9getenv which strdups.

As a convenience to people working on the tools,
leave Makefiles that invoke the go dist tool appropriately.
They are not used during the build.

This makes the full file paths recorded by 6g
prefer $PWD over the actual directory name
(relevant when $PWD gets to the current directory
via symlinks). It's what everyone else does, and
what people expect.

Use OS rather than compiler specific flag the same way that
__FreeBSD__, __APPLE__, __OpenBSD__, and __linux__ are used.
_WIN32 is defined by GCC (and others) on windows for Win32
and Win64 applications. _WIN32 is set by default for several
other windows based compilers: DMC, MSVC, Intel, Watcom, LCC.
Although the change is for consistency, it allows the Go tools
to be compiled with non-Mingw GCC distributions and non-GCC
compilers that support the GCC extensions.
