sim/iq2000: silence pointer-sign warnings
When building the iq2000 simulator I see a few warnings like this:
/tmp/build/sim/../../src/sim/iq2000/iq2000.c: In function ‘fetch_str’:
/tmp/build/sim/../../src/sim/iq2000/iq2000.c:50:54: error: pointer targets in passing argument 3 of ‘sim_read’ differ in signedness [-Werror=pointer-sign]
50 | sim_read (CPU_STATE (current_cpu), CPU2DATA(addr), buf, nr);
| ^~~
| |
| char *
I've silenced these warnings by casting buf to 'unsigned char *'.
With this change I now see no warnings when compiling iq2000.c, so
I've removed the line from Makefile.in that disables -Werror.
Makefile.in was also disabling -Werror when compiling mloop.c,
however, I'm not seeing any warnings when compiling that file, so I've
removed the -Werror disable in that case too.
