Work in progress 1: Seems to build LLIntAssembly.h successfully.

Unfortunately, LowLevelInterpreter.cpp doesn't build on MSVC.  Will need to investigate that next.

A much cleaner patch that forces the llint C++ backend only on the Windows port.

Let's test this against the ews bots.

Does this specifically exclude Win64?

I think yes.  But I didn't add this.  It is simply inherited (copied from) from the rest of the project.  This may have to be revised when/if Win64 support is added.

It broke my git.webkit.org repository:

$ git status
# On branch master
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   Source/JavaScriptCore/JavaScriptCore.vcproj/LLIntAssembly/LLIntAssembly.vcproj
#       modified:   Source/JavaScriptCore/JavaScriptCore.vcproj/LLIntDesiredOffsets/LLIntDesiredOffsets.vcproj
#       modified:   Source/JavaScriptCore/JavaScriptCore.vcproj/LLIntOffsetsExtractor/LLIntOffsetsExtractor.vcproj
#
no changes added to commit (use "git add" and/or "git commit -a")

git checkout ... or git reset --hard HEAD can't fix it.
Have you got any idea what is this problem?

[Csaba Osztrogonác]

... and it killed Qt,GTK,EFL EWS bots with same error.
I cc-ed other guys, maybe you any idea what happens.

[Csaba Osztrogonác]

I think I got the problem. The old vcproj files has the following svn property:
"Property svn:eol-style set to native", but the problematic 3 files don't.

OK, I'll undo the commit, and re-apply to see if that helps.

[Csaba Osztrogonác]

I filed a new bug report to find a general fix for this problem - https://bugs.webkit.org/show_bug.cgi?id=96934

Set svn:eol-style to native in r128777: <http://trac.webkit.org/changeset/128777>.

This change broke the WinCairo build bot.  I'll try to get it sorted out in the morning.
