compile error on binutils head for sparc-rtems4.11

compile error on binutils head for sparc-rtems4.11

[Joel Sherrill]

Hi,

I am compiling the binutils head with the gcc
head from yesterday on Fedora. It is reported
as a gcc error but I thought I would post it here
first.

gcc (GCC) 4.7.0 20111029 (experimental)

I get this when configuring for sparc-rtems4.11 using this
configure command:

/users/joel/test-gcc/binutils-cvs/src/configure \
--target=sparc-rtems4.11 \
--prefix=/users/joel/test-gcc/install-svn \
--disable-werror

You're not an orphan.  I see a similar error compiling CPU2006 445.gobmk
with gcc rev 180588 on powerpc-linux.

Thanks.  I noticed later that arm-rtems tripped
the same bug.  Looks like there are multiple GCC
PRs which appear to be various incarnations:
