And they say ignorance is bliss. I didn't really think about that and
I was just looking at ntdll and msvcrt differences today. What would be
proper
Way to fix this? Once I have the idea, I can do the patches for the
rest.
Mingw include stdlib.h be default and there are at least two other 
functions like this that are in msvcrt and as such mingw.

Not really =). At least not a good one.

My first goal has been to get the wine tree ready to be ported 
then start working my way down. With the latest patches to the build
system 
Alexandre did we can now build wine/programs with almost no problems.
Now I am starting to move in the higher dlls like sh* ole* and com*. 

It was my assumption (I know assumption is the mother of all fuckups)
that 
if dll seperation is done properly, I should just be able to drop them 
in as replacements on NT/2K and see what breaks. Wineserver emulates 
Windows NT/2K be default right? I thought it handled threading and 
such in the same way? From what I gathered at wineconf and what I have 
followed here, There really shouldn't be much work outside of the
already 
planned dll seperation. (Of course we already covered assumption)

At some point I plan on fixing wineserver on cygwin but that is a whole
other project for down the road. At the rate things are going it will be
Another year before I am ready and understand things enough to try.

Thanks
Steven
