Subject: [PATCH] Fix #ifndef statements: HAVE_ variables are all upper case

The autoconf manual states:

   define HAVE_function (in all capitals) if it is available

https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Generic-Functions.html#Generic-Functions

Thanks to @sur5r for the report
