Tarball of preprocessed C and generated assembly

When building newlib using the gcc-svn head, the compiler generates assembly
language that cannot be assembled by the binutils cvs head or 2.22

xgcc (GCC) 4.8.0 20121103 (experimental) [trunk revision 193124]

Attached are the preprocessed C code and generated assembly.

This is sufficient to trip the issue:
