I got a VC++2010 running in 32bit Windows (winXp). Can I still build a 64bit spidermonkey binary using it? Since supposedly I can still build a 64bit exe using the VS IDE so long as I run the generated binary in another true 64bit Windows.
The MozillaBuild has a batch file 'start-msvc10-x64.bat' to start a console whose path point to the 64bit cl.exe. But it seems to me that it can only be called in a 64bit Windows i.e. you need to install VC++2010 in a 64bit Windows first to use this batch file.
