Fixed as follows. Thanks for the report!
2017-04-18 Bruno Haible <br...@clisp.org>
vma-iter: Fix conflict with module 'largefile' on 32-bit Solaris 9.
* modules/vma-iter (configure.ac): Test whether <sys/procfs.h> can be
included.
* lib/vma-iter.c: On Solaris, test HAVE_SYS_PROCFS_H before including
<sys/procfs.h>.
* lib/vma-iter.h (VMA_ITERATE_SUPPORTED): Don't define on Solaris when
<sys/procfs.h> cannot be included.
Reported by Tom G. Christensen <t...@jupiterrise.com>.
