Fix snapshot generation on Visual Studio. Compiling source files generated in...

tools/visual_studio/README.txt

 This directory contains Microsoft Visual Studio project files for including v8
 in a Visual Studio/Visual C++ Express solution. All these project files have
 been created for use with Microsoft Visual Studio 2005. They can however also
 be used in both Visual Studio 2008 and Visual C++ 2008 Express Edition. When
 using the project files in the 2008 editions minor upgrades to the files will
 be performed by Visual Studio.
 
 v8_base.vcproj
 --------------
 Base V8 library containing all the V8 code but no JavaScript library code. This
 includes third party code for regular expression handling (jscre) and
 string/number convertions (dtoa).
 
 v8.vcproj
 ---------
 V8 library containing all the V8 and JavaScript library code embedded as source
 which is compiled as V8 is running.
 
 v8_mksnapshot.vcproj
 --------------------
 Executable v8_mksnapshot.exe for building a heap snapshot from a running V8.
 
+v8_snapshot_cc.vcproj
+---------------------
+Uses v8_mksnapshot.exe to generate snapshot.cc, which is used in
+v8_snapshot.vcproj.
+
 v8_snapshot.vcproj
 ------------------
 V8 library containing all the V8 and JavaScript library code embedded as a heap
 snapshot instead of source to be compiled as V8 is running. Using this library
 provides significantly faster startup time than v8.vcproj.
 
 The property sheets common.vsprops, debug.vsprops and release.vsprops contains
 most of the configuration options and are inhireted by the project files
 described above. The location of the output directory used are defined in
 common.vsprops.
 
 With regard to Platform SDK version V8 has no specific requriments and builds
 with either what is supplied with Visual Studio 2005 or the latest Platform SDK
 from Microsoft.
 
 When adding these projects to a solution the following dependencies needs to be
 in place:
 
   v8.vcproj depends on v8_base.vcproj
   v8_mksnapshot.vcproj depends on v8.vcproj
-  v8_snapshot.vcproj depends on v8_mksnapshot.vcproj and v8_base.vcproj
+  v8_snapshot_cc.vcproj depends on v8_mksnapshot.vcproj
+  v8_snapshot.vcproj depends on v8_snapshot_cc.vcproj and v8_base.vcproj
 
 A project which uses V8 should then depend on v8_snapshot.vcproj.
 
 If V8 without snapshot if preferred only v8_base.vcproj and v8.vcproj are
 required and a project which uses V8 should depend on v8.vcproj.
 
 Two sample project files are available as well. These are v8_shell_sample.vcproj
 for building the sample in samples\shell.cc and v8_process_sample.vcproj for
 building the sample in samples\process.cc. Add either of these (or both) to a
 solution with v8_base, v8, v8_mksnapshot and v8_snapshot set up as described
+solution with v8_base, v8, v8_mksnapshot and v8_snapshot set up as described
 above and have them depend on v8_snapshot.
 
 Finally a sample Visual Studio solution file for is provided. This solution file
 includes the two sample projects together with the V8 projects and with the
 dependencies configured as described above.
 
 Python requirements
 -------------------
 When using the Microsoft Visual Studio project files Python version 2.4 or later
 is required. Make sure that python.exe is on the path before running Visual
 Studio. The use of Python is in the command script js2c.cmd which is used in the
 Custom Build Step for v8natives.js in the v8.vcproj project.
