build error in nrv2b.c on Ubuntu 11.10 32bits

[MrLeV]

Hello -


git cloned today ( git clone git://git.ipxe.org/ipxe.git )

and immediately ran make

The first "make" command failed with this error:

ar: creating bin/blib.a
[HOSTCC] util/zbin
In file included from util/zbin.c:6:0:
util/nrv2b.c: In function ‘find_match’:
util/nrv2b.c:633:17: error: array subscript is above array bounds [-Werror=array-bounds]
util/nrv2b.c:634:14: error: array subscript is above array bounds [-Werror=array-bounds]
cc1: all warnings being treated as errors

make: *** [util/zbin] Error 1


I am using a Ubuntu 11.10 (upgraded from 10.10, upgraded from 10.04) x86 environment in a VMWare guest (but I don't think this is important).
All updates applied. I undertsand what the error mean and that I could even get rid of it by making the build environment considering it a non-stopping warning, but this is not clean and is certainly not expected.

Thanks in advance for your help
