It would help if you didn't present as a fact what is in
reality you personal opinion. Windows or MSVC is only broken
according to *your* criteria, not everybody's. It is very
easy to come up with any number of technical reasons against
any platform you want to declare broken. Whether supporting
C99 is unreasonable or not is depending on a point of view,
and hence isn't a fact either. The same holds for what amount
of support can be considered 'minimal'. gcc's support for C99
goes further than MSVC's, for sure, but isn't complete
either. To presume that its level of support for C99 is
'reasonable' is therefore again a matter of opinion.
That does not make your opinion wrong, but it separates it
from a fact, and it prevents your decisions from being purely
based on technical reasons. Your reasons are no more or less
technical than those put forward by the M$-users here.
I'm not demanding that you subscribe to my point of view, but
insisting on your point of view being the right one is
patronizing, and pretending that it is technical and purely
based on fact is not credible.

So what is the point in one group of ffmpeg developers not
wanting to talk with another group of ffmpeg developers?

But it was there before, through EMULATE_INTTYPES, so what is

MSVC does not even *want* to be C99 compliant, so the problem
isn't with its headers. They are ok for what they aspire to
be. The problem is what level of C99 compliance is to be
required from C compilers which are used for projects using
ffmpeg (not for those used to compile ffmpeg). And that is
again largely not a technical, but a strategic question. It
is a function of the platforms you want to support. End of

On that level there aren't any requirements at all for
projects conducted by volunteers. That's why I don't talk
about requirements. I'm trying to be pragmatic, that's all,
and I'd prefer if others were pragmatic, too.

They might not agree with your opinion that it is deficient
in the first place. They may instead hold the opinion that
ffmpeg itself is deficient. That probably won't make any
particular difference to you, but it shows again that we're
in the realms of personal opinions, and not the realms of

I don't think that anyone would demand that you or any of the
other "core" developers add another platform to the ones you
check on a regular basis. I am confident that the developers
using MSVC would do that themselves, and howl here when
something has stopped working, if only they had the feeling
that they are being accepted as part of the community here.
Facing the same old battle each time a patch is proposed does
not create this feeling however. Your being so dismissive
contributes in creating the problem you moan about.

Given what I wrote above, I hope you can appreciate that this
sounds quite patronizing to those who happen to differ from
your point of view. Let me paraphrase this to get my point
I don't care about what's broken, as we know that this
depends on the point of view. Now I'd appreciate if the
ffmpeg developers acknowledged the existence and the
interests of developers having to use said platform for

I hope I could make clear what it is in your stance that
comes across as provoking.
