Note:

By default the Makefile defines 'CC=gcc -std=gnu99' and because we
automatically pass 'CC=gcc' as make argument which overwrites the
the needed '-std=gnu99' we need to workaround the problem manually

Note:

This is a "blind update" because we need to package alien-sdl available from
http://search.cpan.org/dist/Alien-SDL/ to be able to build SDL-Perl!

Thanks to karasz for providing the patch!

The use of including <curl/types.h> was deprecated more than 7 years ago,
and the header file was finally removed with the release of curl 7.21.7.

Reference how upstream changed their own example code:
