As discussed in issue19273, here are a pair of patches that correct factual errors in PCbuild/readme.txt in both 2.7 and 3.3.

The 3.3 patch makes the following changes:
- Remove Win2k mentions, it is not supported (Tcl nmake command also adjusted)
- MSVCRT9 -> MSVCRT10
- SQLite 3.7.4 -> 3.7.12, remove "(see below)" with nothing to see
- .vcproj -> .vcxproj, all occurrences 
- _bz2.vcxproj isn't as magical as it was made out to be, and it can clean itself
- nasmw -> nasm
- Remove untrue part of Building for Itanium section
- Update msdn link
- .vsprops -> .props
- Trim trailing space

Due to the large number of lines in the diff due to trailing space, I'll also be attaching a patch created by `hg diff -w` for ease of review.

The 2.7 patch makes the following changes:
- python30.dll -> python27.dll
- remove "(see below)" from _bsddb and _sqlite3 which have nothing to see below
- bz2.vcproj isn't as magical as it made out to be, and it can clean itself
- nasmw -> nasm
- Remove untrue part of Building for Itanium section
- Update msdn link
- Trim trailing space

There is also a diff -w patch for 2.7, due to the large number of lines with trailing space.

Zachary, perharps you could make a diff with mercurial so we can have Rietveld review link. I don't know whether git can do that or not.

These diffs are produced by `hg diff --git`.  If I'm not mistaken, the reason there is no review link is because these patches are not against default branch.  Here's one without the `--git` option though, just to see if I'm wrong :).  If I am, I'll replace all of them.

How wrong I was...

With the --git option, the rietveld service only tries against the default branch.  Without the --git option, it can figure out the changeset the patch is based against and use that.

Both patches look fine to me.

Thanks for the lesson, Vajrasky and David, and thank you for the review Brian.

The final commit did have a couple changes not in the posted patch, just fixes of the same two obvious typos in both branches (avalible -> available, lniked -> linked).
