Details:
(Reported by Vladimir Vukicevic on the mozilla bug tracker)
make 4.0 can't handle long path names, which need some special magic under
windows -- you need to use the unicode versions of the IO functions, and
prepend paths with the \\?\ UNC prefix. (Note that also turns off automatic /
-> \ conversion.) So, \\?\C:\foo\bar\baz instead of C:/foo/bar/baz or
similar.
STR:
$ cd c:/tmp # or wherever
$ mkdir -p

$ cd !$
$ echo hello > this-is-a-long-filename.txt

needed by 'success'. Stop.
