Frank, Alan: thank you for your help. I have dug a lot around stdio, and I 
understood a lot of things.

I'm currently working on a patch for the MiNTLib, it fixes some gmp 
testcases, but not yet all of them. I hope it will be finished in a few days.

Alan, your patch was very good starting point.
The missing _IOMAGIC value was the first cause of failure. It can't work 
without it. But adding it is not enough.

I noticed a "bad smell": you added the following line:
(void) obstack;
to avoid compiler warnings about the unused parameter.
You're right, it isn't used. But it should !

After a lot of debugging, I went to the conclusion that the whole file 
obstream.c is totally broken, and cannot work in any case. I started to 
rewrite it completely, it is very similar to vasprintf.c, which is good.

I hope it will be ready soon (very boring work).
