[patch] Can't build ppc32 GDB

[PAUL GILLIAM <pgilliam at us dot ibm dot com>]

I don't know if all ppc systems have this problem.  But on a PowerPC-64
system, I get the following when I try to build a 32-bit gdb:

gcc -c -g -O2  -mminimal-toc  -I. -I.././gdb -I.././gdb/config
-DLOCALEDIR="\"/usr/local/share/locale\"" -DHAVE_CONFIG_H
-I.././gdb/../include/opcode -I.././gdb/../readline/.. -I../bfd
-I.././gdb/../bfd -I.././gdb/../include -I../intl -I.././gdb/../intl
-DMI_OUT=1 -DTUI=1 -Wimplicit -Wreturn-type -Wcomment -Wtrigraphs
-Wformat -Wparentheses -Wpointer-arith -Wformat-nonliteral
-Wunused-label -Wunused-function -Wno-pointer-sign -Wuninitialized
-Werror ppc-linux-nat.c
cc1: warnings being treated as errors
ppc-linux-nat.c: In function âfetch_registerâ:
ppc-linux-nat.c:396: warning: cast to pointer from integer of different
size
ppc-linux-nat.c: In function âstore_registerâ:
ppc-linux-nat.c:691: warning: cast to pointer from integer of different
size
ppc-linux-nat.c: In function âppc_linux_stopped_by_watchpointâ:
ppc-linux-nat.c:904: warning: cast from pointer to integer of different
size
make: *** [ppc-linux-nat.o] Error 1


So as a starting point, I have attached a patch that gets rid of the
warnings.

OK to commit? (not expecting a 'yes', but you never know unless you ask
8-)
