[Bug c/24894] New: ICE building newlib/libc/misc/init.c


GCC head as of 16 Nov with newlib 1.13.0.  Configured as follows:

../gcc-head-test/configure --target=avr-rtems4.7 --enable-threads=rtems
--prefix=/home/joel/gcc-41-test/ --with-gnu-as --with-gnu-ld --with-newlib
--verbose --with-system-zlib --disable-nls
--enable-version-specific-runtime-libs --enable-languages=c

Fails with this:
