make_perl_groups.pl is copied with minimal modifications
(just to generate Go syntax instead of C++) from RE2.
Google Inc is "The RE2 Author" of that file and is one of
the Go Authors, so copyright changed to the Go Authors instead.

The "elf.h" header changes involve only comments, the released
Plan 9 C preprocessing function does not cope with multiline
comments following the #define keyword. All multiline comments
have been moved to the line above the associated definition.
Sigh! Fixing the Plan 9 compiler is not an option.
<time.h> does not exist in the Plan 9 Native library. I have
moved it from src/cmd/ld/pe.h to include/u.h. RSC correctly points
out that this copy of <u.h> is not the one used to compile the
Go release on Plan 9 platforms.

If we fail due to a missing command (always bison)
during the build, it is running many things in parallel
and the error message gets lost in the noise.
Also diagnose bison++.
$ ./make.bash
Your system's bison is bison++, a buggy copy of the original bison.
Go needs the original bison instead.
See http://golang.org/doc/install.html#ctools
$ sudo apt-get remove bison++

Parser is a work in progress but can populate most of the
interesting parts of the data structure, so a good checkpoint.
All the complicated Perl syntax is missing, as are various
important optimizations made during parsing to the
syntax tree.
The plan is that exp/regexp's API will mimic regexp,
and exp/regexp/syntax provides the parser directly
for programs that need it (and for implementing exp/regexp).
Once finished, exp/regexp will replace regexp.

Via Russ Ross' bug report on golang-nuts, it was not possible
to send an HTTP request with a zero length body with either a
Content-Length (it was stripped) or chunking (it wasn't set).
This means Go couldn't upload 0-length objects to Amazon S3.
(which aren't as silly as they might sound, as S3 objects can
have key/values associated with them, set in the headers)
Amazon further doesn't supported chunked uploads. (not Go's
problem, but we should be able to let users set an explicit
Content-Length, even if it's zero.)
To fix the ambiguity of an explicit zero Content-Length and
the Request struct's default zero value, users need to
explicit set TransferEncoding to []string{"identity"} to force
the Request.Write to include a Content-Length: 0. identity is
in RFC 2616 but is ignored pretty much everywhere. We don't
even then serialize it on the wire, since it's kinda useless,
except as an internal sentinel value.
The "identity" value is then documented, but most users can
ignore that because NewRequest now sets that.
And adds more tests.

Ian Taylor's suggestion. It fixes all.bash failing with

Three optimizations: First, special-case power of two bases
that partion a Word(), bases 2, 4, 16, and 256. These can
be moved directly from internal Word() storage to the output
without multiprecision operations. Next, same approach for
the other power-of-two bases, 8, 32, 64, and 128. These
don't fill a Word() evenly, so special handling is needed
for those cases where input spans the high-bits of one Word
and the low bis of the next one. Finally, implement the
general case for others bases in 2 <= base <= 256 using
superbases, the largest power of base representable in a
Word(). For base ten, this is 9 digits and a superbase of
10^9 for 32-bit Words and 19 digits and 10^19 for 64-bit
compiles. This way we do just 1/9th or 1/19th of the expensive
multiprecision divisions, unpacking superdigits using fast
native machine arithmetic. The resulting code runs 7x to
800x the speed of the previous approach, depending on the
length of the number to be converted--longer is relatively
faster.
Also, extended the tests and benchmarks for string to nat
(scan()) and nat to string (string()) functions. A further
enhancement awaits the next CL to make general cases about
7x faster for long cases.

I started looking at this code because the nm in GNU
binutils was ignoring the first symbol in the .symtab
section. Apparently, the System V ABI reserves the
first entry and requires all fields inside to be set
to zero.
The list of changes is as follows:
· reserve the first symbol entry (as noted above)
· fix the section indices for .data and .bss symbols
· factor out common code for Elf32 and Elf64
· remove the special case for elfsymo in [568]l/asm.c:/^asmb
· add the "etext" symbol in 6l
· add static symbols

add QuoteToASCII.
The Quote and QuoteRune functions now let printable
runes (as defined by unicode.IsPrint) through. When
true 7-bit clean stuff is necessary, there are now two
new functions: QuoteToASCII and QuoteRuneToASCII.
Printf("%q") uses Quote. To get the old behavior, it
will now be necessary to say
Printf("%s", strconv.QuoteToASCII(s))
but that should rarely be necessary.

This change moves a number of common PKIX structures into
crypto/x509/pkix, from where x509, and ocsp can reference
them, saving duplication. It also removes x509/crl and merges it into
x509 and x509/pkix.
x509 is changed to take advantage of the big.Int support that now
exists in asn1. Because of this, the public/private key pair in
http/httptest/server.go had to be updated because it was serialised
with an old version of the code that didn't zero pad ASN.1 INTEGERs.
