   User mode support for Linux ELF files with no section header (2014-06-09 
 15:19:59 +0300)

Hi; I'm afraid this fails to build for me when building
m68k-linux-user:

/root/qemu/linux-user/signal.c: In function 'target_rt_restore_ucontext':
/root/qemu/linux-user/signal.c:5079:5: error: 'err' may be used
uninitialized in this function [-Werror=uninitialized]

because the function never sets 'err' but then
returns it.

(32-bit, ARM, gcc 4.7.2. I don't know why the other
compilers don't spot this; perhaps they inline the
function and then figure out that the unused return
value isn't actually ever used.)

thanks

Ok, I'll fix this and send another round. I'll also see some older
toolchain for testing.
