Here's the test which reproduces this https://lkml.org/lkml/2015/5/30/98

Should run on at least Debian based distributions and some cross compilers.
In the end the script generates a .c file which includes only this header file
and tries to compile it with a call like:

cc -Wall -c -nostdinc -I /usr/lib/gcc/i586-linux-gnu/4.9/include -I /usr/lib/gcc/i586-linux-gnu/4.9/include-fixed -I . -I ../headers_compile_test_include -I ../headers_compile_test_include/i586-linux-gnu ./linux/netfilter/ipset/ip_set_bitmap.c
