So, it seems that our pixman 0.16.0 header has a genuine redundant
declaration, not influenced by qemu-pixman.h. I worked around it by
manually changing -Wredundant-decl to -Wno-redundant-decl in configure,
similar to what some FreeBSD versions needed. Suggestions for a real
warnings-fix or configure-detection of incompatible headers appreciated!
