--- Comment #2 from Lei Zhang thestig@google.com 2009-08-18 22:38:48 --- This bug is probably invalid. I think happens on Windows also. Try running cl.exe on Windows from cmd.exe. To get it to work on Windows, you have to run vcvarall.bat first. I think the magic bit is that it adds C:\Program Files\Microsoft Visual Studio 8\Common7\IDE to the PATH.
