For all the other stuff it makes nice and portable...? SDL is use in 
plenty of applications that do various things in platform specific 
ways.

Kodo Deluxe (of course! As if I'd ever miss a chance to mention it! 
 is one of them - and it still runs on some 20 different OS/CPU 
combinations. No big deal - just a few #ifdefs, and some weird 
features that no one will miss, that work only on Linux. (Especially 
true if some of the platform specific code is contributed by others, 
so you don't have to hack it yourself! 

> Personally I use SDL because it is cross-platfrom

Sure, and I think the majority of us do. However, I don't see what's 
wrong with giving some users some bonus features - especially if it's 
stuff that could later be implemented on some other platforms as 
well. Platforms are not identical. Some just don't provide certain 
features at all. Does that mean you shouldn't use those features at 
all, on any platform...?

A couple of questions...

Before I go running off re-inventing the wheel (my version would undoubtedly
look remarkably like a square), I wanted to see if any of you have already
developed solutions for them:

1) I need to be able to read a source Rect from a bmp and rotate it 90
degrees.
2) Copy one SDL_Surface to another.
3) take a Rect and apply different levels of alpha, i.e., make one color
fully transparent and then apply a % to the remainder of the image.

I can go about these using brute force techniques but wanted to see if
anyone out there had a more graceful solution.
Thanks,

It's just the libtool section of acinclude.m4 and ltconfig and ltmain.sh
in the SDL source archive.

I'm not sure if you recall but remember I emailed you about this problem 
with getting Borland 5.02 to work with SDL? The problem with the current 
make file is, I think, that it's created with Borland C++Builder 6 so 
it's unlikely that 5.02 will recognize the files.

You mention that it might be possible to convert it into a format 5.02 
will recognize. Perhaps revising and appending a walkthrough or a 
tutorial to the current existing documentation is a good idea I think.

I can update my system, but I don't like that idea. It would mean that 
all users of my game would have to upgrade their systems. If you rebuild 
the library to work with icmp.dll, would it work on newer Windows 
versions? As far as I read on the net, it probably will not. Or, perhaps 
to detect windows version and do The Right Thing(TM)?

There is an alternative to these techniques, that should work on all 
Windows platforms, take a look at this article and code:

http://www.tangentsoft.net/wskfaq/examples/rawping.html

However, I'm not an expert on this subject, but it would probably mean 
something to you.

Ok. I was only going to use fast route ping anyway. I want to use it 
upon initial connection, to check wheter the other side is "there". It 
seem a lot more simple that using UDP for the same thing.

In fact, all would be good if we could have a function to reduce the 
timeout of TCP's Connect() function. I also found an article about this, 
but I'm not sure whether the other platforms have a similar thing:

http://www.tangentsoft.net/wskfaq/newbie.html#timeout

If would be great addition to SDL_net to have a function like:
SDLNet_SetTimeout(int seconds);

Re: SDL_Mixer doesn't like SOME oggs

I've experienced the same problem. Just solved it by encoding the OGG 
files with the parameters that SDL_mixer accepts...

This can be done in less than 10 lines of code. Just write two nested 
for loops to copy the pixels to the right place on destination ;)

This is even easier, one liner.

Hm, don't know about this one... what exactly do you want to do?
