GUB again

[Phil Holmes]

Right,

I'm back from holiday and able to try getting GUB to run again.  As a 
reminder, I have gcc version 4.8.2 running on a 32 bit incarnation of 
Ubuntu 14.04 running in a VM.  It fails to build librestrict with this 
(and other) errors:

gcc -W -Wall -fno-stack-protector -I. -fPIC -shared -o librestrict-stat.so 
restrict-stat.c
In file included from restrict-stat.c:106:0:
./xstatconv.c: In function ‘__xstat_conv’:
./xstatconv.c:90:5: error: ‘struct stat’ has no member named ‘__unused4’
buf->__unused4 = 0;
^

librestrict appears unchanged for ages, so it must be a problem with 
another part of the system: with gcc perhaps?  4.8.2 appears to be the 
default installation on this version of Ubuntu: it's certainly in usr/bin.

I've seen a proposed patch from Masamichi, but as David says, this may fix 
the issue but doesn't shed any light on what is the root cause.  Is it 
worth trying to go back to an earlier version of gcc?  If so, how would I 
go about that?

Thanks.

Phil
