[Scons-users] env.command fails on mingw shell

[Evan Driscoll]

The following works for me:

from SCons.Platform.win32 import exec_spawn

import os
env = Environment(ENV = {'PATH' : os.environ["PATH"]})
env["SHELL"]=env.WhereIs("bash")
env["SPAWN"] = (lambda sh, esc, cmd, args, env_param:
                exec_spawn([sh, '-c', ' '.join(args)], env_param))
env.Command("test", "", "ls;")


You may wish to factor out the definition of env["SPAWN"] to a named
function, and of course you must only set that on Windows.
