Cross compiling to host=i586-mingw32msvc I encountered 2 problems related to include_next.m4.
Firstly I had to apply the attached patch to avoid configure complaining about missing operands. Secondly, I had to put gl_INCLUDE_NEXT in configure.ac which I was rather surprised about. Since it's a dependency of rather a lot of modules I had expected it to already be indirectly included.
