d4ca006334 math: 386 FPU hypot
Added 386 FPU version of Hypot; modified all_test.go to test
Hypot with large arguments.  Also edited sqrt.go to remove
Sqrt(0) as a special case.

718be3215f in C and asm, replace pkg·name with ·name
(eliminate assumption of package global name space,
make code easier to move between packages).

a3d1045fb7 1) Change default gofmt default settings for
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.

6fc820729e go: makes it build for the case $GOROOT has whitespaces
the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.

this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.

Fixes #115.

3b864e4195 convert low-level (used by testing) packages to
whole-package compilation.  new Makefiles,
tests now in separate package

	bytes
	flag
	fmt
	io
	math
	once
	os
	reflect
	strconv
	sync
	time
	utf8

delete import "xxx" in package xxx.

inside package xxx, xxx is not declared
anymore so s/xxx.//g

delete file and package level forward declarations.

note the new internal_test.go and sync
and strconv to provide public access to
internals during testing.  the installed version
of the package omits that file and thus does
not open the internals to all clients.
