The new //export comment marks a Go function as callable from
C. The syntax is "//export NAME" where NAME is the name of
the function as seen from C. If such a comment is seen, cgo
will generate two new files: _cgo_export.h and _cgo_export.c.
The _cgo_export.h file provides declarations which C code may
use to call Go functions. The _cgo_export.c file contains
wrappers, and is to be compiled with gcc.
The changes to Make.pkg support using this from a Go Makefile,
though it could probably be more convenient.

only the formatting of the day initializers changed.
i'm happy to revert that formatting if you'd prefer.

- 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.

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.

Ideally, the C name would come from the typedef or pointer that
references the Size<0 type, but we can't easily generate this without
performing a look-ahead to see if any referencing type will become opaque.

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.

Firstly, with -Werror, GCC switched to printing warnings starting
with "error:". Widening the string matches solves this as the messages
are otherwise unchanged.
Secondly, GCC 4.4 outputs DWARF sections with with NUL bytes in all
the offsets and requires the relocation section for .debug_info to be
processed in order to result in valid DWARF data. Thus we add minimal
handling for relocation sections, which is sufficient for our needs.

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.
