For the weekend, i planned to add a BR2_PREFER_IMA to buildroot and will then redo the patch for uClibc's GETC/PUTC in order not to pollute the (visible) namespace. After that i can try to read and/or reproduce the problem you were seeing with stdio (offhand i don't remember what it was about nor if i read it in the first place, fwiw). Then there is also whirm's soekris update that sounds like i should generalize the so called generic x86 support i added for my own convenience to be more generic. That'd allow for using the linux26 kernel for non-i386 and non-soekris devices with just an updated platform/board dependant linux.config. I also like to try out the patch for bug #881 while i'm building buildroot anyway. There are also some shrinkages for busybox and uClibc that i ment to send out, we'll see if i find enough time to take care of those this weekend.. And there's also Ulf's atmel patches which will have to wait for the soekris/ia32 addition and cleanup to be finished first, fwiw.
