[pacman-dev] [PATCH] configure.ac: add checks for more types, functions and headers

[Allan McRae]

This covers most types, functions and headers that we use in the
code base.  Currently we do not use any of these checks, but it
is useful to have the configure output when looking at build issues
on other peoples systems.

The only other check I wanted to add was AC_FUNC_STRNLEN, but that gives
me autoconf warnings that look like an upstream issue so I have left it out
for now.
