Hi,
> My version of patch to fix same problem:
Oh, yes. You are right.
I have read manpage again, and I found it says,
if size is zero, list is not modified, but ...
So, mine is wrong. We should check only "size".
/yoshii
getgroups() and getgroups32() returns NGROUPS_MAX when both its two args are
zero. But because we pass a ptr to allocated space as 2nd arg, this function
are interfered. The patch attached fixed it.

Hi,
I succeeded to build "system" set of packages on Gentoo Linux, which is
a small root filesystem with toolchain(because it is essential for Gentoo),
inside a chroot environment with qemu-linux-user emu.
Several instructions for sh4 need to be fixed/added.
Some fixes and workarounds are needed
Hi,
I found some instructions missing on SH4, and added some.
Graphics extentions(like sin/cos/sqrt/vector op) are still missing,
but I believe no one need them, at least, so far.
"fneg" is implemented as 32bit op, according to the programming manual.

Small patch around execve again.
Now unlinkat() goes through into execve. Here is the fix.
