Subject: Re:  build error from compiler warning for -Werror

Sorry for the in-convenience.

I still can re-produce the bug from CVS-20090120.

gcc -g -O2   -I. -I../../src/gdb -I../../src/gdb/config
-DLOCALEDIR="\"/home/robert_bu/local/gdb-cvs/share/locale\""
-DHAVE_CONFIG_H -I../../src/gdb/../include/opcode

-I../../src/gdb/../include -I../libdecnumber
-I../../src/gdb/../libdecnumber  -I../../src/gdb/gnulib -Ignulib

My host is a Redhat Enterprise 3. The GCC is:
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit
--host=i386-redhat-linux
Thread model: posix
gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-54)

I have to initialize funaddr to NULL to compile CVS gdb.
