Getting, building and installing ObjFW
--------------------------------------

  Start the MinGW-w64 Win32 or Win64 Shell (depening on what version you want

  to build) and check out ObjFW:

    $ git clone https://webkeks.org/git/objfw.git

  You can also download a release tarball if you want. Now go to the newly
  checked out repository and build and install it:

    $ ./autogen.sh && ./configure && make -j16 install

Getting, building and installing ObjFW
--------------------------------------

  Start the MinGW-w64 Win32 or Win64 Shell (depening on what version you want
  to build - do *not* use the MSYS2 Shell shortcut, but use the MinGW-w64 Win32
  or Win64 Shell shortcut instead!) and check out ObjFW:

    $ git clone https://webkeks.org/git/objfw.git

  You can also download a release tarball if you want. Now go to the newly
  checked out repository and build and install it:

    $ ./autogen.sh && ./configure && make -j16 install

Modified configure.ac from [f7868ab464] to [3a659041ab].
