Hi, after a year, I decided to hack on klibc again. I?ve reworked both the patch to add mkstemp(), discussing to use AT_RANDOM as cheap entropy source on IRC (if there will ever be another entropy consumer, I can quickly write a minimal arc4random() seeded from it, as it has only 16 octets), capable of making a working mksh (static and shared) on amd64/xen, and the m68k support code, leading to

Hi, I?ve gone through the mailing list archives and hereby want to resubmit my pending patches. Most are independent of each other, except the m68k patch which will only be complete if sigsuspend is also fixed. (It can be applied before that, though.) http://www.zytor.com/pipermail/klibc/2012-January/003173.html [PATCH] fix m68k support Resubmitted here as 0005. While there was a question from

Hi, number three, where I first thought it was a GCC bug but is apparently bad code in klibc. Submitted with permission: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47533#c6 Patch attached again (sorry) not just because that is easier with my mail system but also to keep original author intact. bye, //mirabilos -- > emacs als auch vi zum Kotzen finde (joe rules) und pine f?r den einzig >

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
