If it's supported by Windows then I'm OK (not that I personaly care
about Windows :-).

Well, I'd rather have this flag called 'x', to be consistent with
c (since glibc 2.3.3)
Do not make the open operation, or subsequent read and write
operations, thread cancellation points.
x Open the file exclusively (like the O_EXCL flag of
open(2)). If the
file already exists, fopen() fails, and sets errno to
flag is ignored for fdopen().
By the way, could you submit your patch as a mercurial diff ("hg diff")?
It makes it easier to review under Rietveld.
