[New-bugs-announce] [issue20445] HAVE_BROKEN_NICE detected incorrectly due to configure.ac typo

[George Kouryachy]

New submission from George Kouryachy:

It's declared in pyconfig.h that HAVE_BROKEN_NICE is set if nice() returns success/failure instead of the new priority.

But configure checks just opposite (as for http://hg.python.org/cpython/file/03fc7449f204/configure.ac#l4234):

  if (val1 != -1 && val1 == nice(2))
    exit(0);

We need "val1 != nice(2)" instead (to ensure that nicelevel is increased) or "val1 == nice(2)+2" (to check increment is proper; this can be tricky in some cases).
