0432f289f7 cgo: various bug fixes 
* remember #defined names, so that C.stdout can refer
  to the real name (on OS X) __stdoutp.
* better handling of #defined constant expressions
* allow n, err = C.strtol("asdf", 0, 123) to get errno as os.Error
* write all output files to current directory
* don't require gcc output if there was no input

Fixes #533.
Fixes #709.
Fixes #756.

01b4f2dd23 Steps towards tracking scopes for identifiers. 
- Identifiers refer now to the language entity (Object)
	  that they denote. At the moment this is at best an
	  approximation.

	- Initial data structures for language entities (Objects)
          and expression types (Type) independent of the actual
	  type notations.

	- Initial support for declaring and looking up identifiers.

	- Updated various dependent files and added support functions.

	- Extensively tested to avoid breakage. This is an AST change.

a8fbf5dc2c This patch enables cgo utility to correctly convert enums in the C source 
into consts in the resulting Go source.  Previously known as issue 161047,
which I deleted accidentally.  Fixes issue 207.

5a1d3323fe 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

	       1st set of files.

133a158bd8 8c, 8l dynamic loading support. 
better mach binaries.
cgo working on darwin+linux amd64+386.
eliminated context switches - pi is 30x faster.
add libcgo to build.

on snow leopard:
  - non-cgo binaries work; all tests pass.
  - cgo binaries work on amd64 but not 386.
