I am running into a problem building a multilib version of libatomic. Because of how I configure GCC (building the mips-linux-gnu target with the --with-synci option) some compilations will always generate a warning while compiling the libatomic files. See http://gcc.gnu.org/ml/gcc/2012-06/msg00100.html for details.
This causes the libatomic build to fail because it is compiled with -Werror which is added in the configure script. None of the other libraries seem to be built with -Werror. Can we take this out? Or should it be replaced by AC_PROG_CPP_WERROR? I looked at the definition of AC_PROG_CPP_WERROR in config/acx.m4 and I see it sets ac_c_preproc_warn_flag to 'yes' but it is not clear to me what affect that has in the configure script, if any. I would be happy to submit a patch for this, I am just not sure what the right fix is. Steve Ellcey sell...@mips.com
