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

Commit 8418552 ("[klibc] ia64: Fix shared build") missed this use of the GP register, although the code appears to have been dubious anyway, assuming the address of errno was the first thing pointed to by GP. --- usr/klibc/arch/ia64/vfork.S | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/usr/klibc/arch/ia64/vfork.S b/usr/klibc/arch/ia64/vfork.S index
