No, that's not my argument. Please don't put words into my mouth,
especially not when they are unrelated to what I actually said.

Thank you for that information. Where did you find this out?
Is this guaranteed by some standard? Or is it just your assumption?
Are you sure that some future system won't treat the "t" flag in
fopen as say the "time bomb" option?

That is a fair point. Since using O_TEXT in this way might improve
portability, I'm not opposed to adding support for O_TEXT to gnu-win32.
However, I think that for consistency it would probably not be a good
idea to add O_TEXT without adding support for "t" in fopen, and for
reasons explained above I am still opposed to doing that, though
perhaps you may be able to persuade me otherwise, if you can convince
me of the truth of your claim that
"including a "t" flag in a fopen call does not decrease
portability in any way, as it will simply be ignored by any
libraries which do not support it".

My arguments may perhaps be incorrect, but labelling them as
"egocentric" doesn't add anything to the debate. The quality and
usefulness of this mailing list would be improved if the participants
avoided ad-hominem attacks.
