dragora-nk/patches/gtk2/configure-Move-all-includes-to-the-first-argument-of-AC_T.patch

Subject: configure: Move all includes to the first argument of AC_TRY_LINK

Putting includes in the second argument of AC_TRY_LINK is not safe. If
a header having inline functions is included inside the main function,
it becomes a nested function. This is not supported by clang.

Bug: https://bugzilla.gnome.org/show_bug.cgi?id=792720
Origin: upstream, 2.24.33, commit:c3ededb119405c26c684cef569177b73255b7a22
