todo_wine help

[Phil Lodwick]

I have a test in msvcrt/file.c that requires there be no TMP environment
variable.  I thought I would just do a _putenv("TMP="), but this seems to
interfere with todo_wine.

Basically,

static void test_todo( void )
{
  todo_wine {
  ok((1 == 1), "This shows up correctly\n");
  }
  _putenv("TMP=");
  todo_wine {
  ok((1 == 1), "This does not show\n");
  }
}

My quick search has not turned up anything obvious.  Can somebody help me
understand what is going on here?  Assuming TMP is actually required by
somebody else, how do I correctly do my test and check with no TMP
environment variable?

Thanks,
Phil
