[Bug c/19494] New: Building gcc-3.4.3 fails on gcc/unwind-dw2.c

["emteeoh at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

I'm trying to build LinuxFromScratch.org book 6.0 on a DecAlpha. LFS chapter 5
pass1 and pass2 complete with no errors, but gcc-3.4.1 *AND* gcc-3.4.3 both fail
when trying to compile gcc/unwind-dw2.c in chapter 6 (the big difference being
that in chapter 6, I'm building in the bootstrapped environment for installation
into /usr, rather than linked against libraries in /tools/lib and installed into
/tools/bin. I don't understand why it makes a difference...)

gcc -v for the compiler being used to make gcc-3.4.3:
Reading specs from /tools/lib/gcc/alphaev56-unknown-linux-gnu/3.4.1/specs
Configured with: ../gcc-3.4.1/configure --prefix=/tools --libexecdir=/tools/lib
--with-local-prefix=/tools --enable-clocale=gnu --enable-shared
--enable-threads=posix --enable-__cxa_atexit --enable-languages=c,c++
--disable-libstdcxx-pch
Thread model: posix
gcc version 3.4.1
