- Increase required version to 2.60 since that is documented
  minimum version for AC_USE_SYSTEM_EXTENSIONS
- Remove obsolete macros AC_C_CONST and AC_C_VOLATILE. They
  are noops on every compiler we support.
- Add explicit call to AC_PROG_CC. We get this implictly as
  dependency of other macros, but it is nicer to have it
  explicitely as well.
- A few typo and whitespace fixes.

I admit that I have no deep understanding of autoconf, but I did check
that "about everything" has more recent autoconf versions than 2.60
("the gold standard" has been 2.69 for many years) and that all our
buildbots and GHA are building fine with these changes.  Half of them
are typo fixes or whitespace cleanups anyway :-)

Your patch has been applied to the master branch.
