Oh wow, I don't see the first error on x86_64-linux (for
swap_linux_prpsinfo32_ugid32_out) when the preprocessed source looks
like the following.  However, take out the file/line directives and
the problem appears!

static inline void
swap_linux_prpsinfo32_ugid32_out
  (bfd *obfd,
   const struct elf_internal_linux_prpsinfo *from,
   struct elf_external_linux_prpsinfo32_ugid32 *to)
{
  ((void) (*((unsigned char *) (&to->pr_state)) = (from->pr_state) & 0xff));
  ((void) (*((unsigned char *) (&to->pr_sname)) = (from->pr_sname) & 0xff));
  ((void) (*((unsigned char *) (&to->pr_zomb)) = (from->pr_zomb) & 0xff));
  ((void) (*((unsigned char *) (&to->pr_nice)) = (from->pr_nice) & 0xff));
  ((*((obfd)->xvec->bfd_putx32)) ((from->pr_flag),(to->pr_flag)));
  ((*((obfd)->xvec->bfd_putx32)) ((from->pr_uid),(to->pr_uid)));
  ((*((obfd)->xvec->bfd_putx32)) ((from->pr_gid),(to->pr_gid)));
  ((*((obfd)->xvec->bfd_putx32)) ((from->pr_pid),(to->pr_pid)));
  ((*((obfd)->xvec->bfd_putx32)) ((from->pr_ppid),(to->pr_ppid)));
  ((*((obfd)->xvec->bfd_putx32)) ((from->pr_pgrp),(to->pr_pgrp)));
  ((*((obfd)->xvec->bfd_putx32)) ((from->pr_sid),(to->pr_sid)));
