--- Comment #1 from Joel Sherrill <joel at gcc dot gnu.org> --- This patch cannot be merged as is. It includes at least 4 separate issues. + v850 multilibs + sparc64-rtems definining SVR4 + WCHAR issues + stddef.h issue Patches can only be single issue. I am going to use this PR to address the v850 multilib. A new patch will come in a few minutes.
