configure.ac: macro calls may be underquoted

http://www.gnu.org/software/hello/manual/autoconf/Autoconf-Language.html

"""
Arguments should be enclosed within the quote characters ‘[’ and ‘]’, 
and be separated by commas.
"""

The page goes on to provide an example where quoting isn't require and goes on 
to say:

"""
Cautious Autoconf users would keep the quotes, but many Autoconf users find 
such precautions annoying...
"""

Personally, I am a cautious autoconf user, and wanted to bring this to your 
attention.

These are the calls to AC_CHECK_HEADERS(stdint.h stddef.h), 
AC_CHECK_FUNC(mmap), AC_SUBST([ac_cv_etc., and the four AC_SUBST() near the 
bottom, right? The m4_define, in particular, should stay as-is?

Yes, but also the arguments to the AC_DEFINE calls. I'd quote the first 
argument to m4_define, because that's what the GNU M4 manual does: 
http://www.gnu.org/software/m4/manual/html_node/Define.html#Define

Note that autoconf changequotes to [] instead of `' for quotation.
