Bug#723803: fix for arm/powerpc/s390 test failures

[Rebecca N. Palmer]

src/simulator/wireframe-simulator/core/vpLex.c assumes that the plain 
chars CURC and NEXTC can hold -1 (EOF) or -2 (EOB), and hence fails if 
char is unsigned.

This is the default on arm*/powerpc/s390, hence this bug, and can be 
tested elsewhere using -funsigned-char.  The attached fixes this by 
explicitly casting them to signed char.

I don't know what's wrong on ia64; given that the last "successful" 
build on it was before the test suite was added (and hence may well be 
just as broken), and that this package is a transition blocker for 
coin3/opencv2.4/libav9, would it make sense to remove it on that 
architecture?
