Google's suggestion is to to include png.h last (after the system header
that redefines jmpbuf), but alas that is already the case within
cairo-png.c. So we have to try the other approach and to undef jmpbuf
within cairo-png.c, viz:

diff --git a/src/cairo-png.c b/src/cairo-png.c
index ee7e5fd..c79b543 100644
--- a/src/cairo-png.c
+++ b/src/cairo-png.c
@@ -40,6 +40,8 @@
 #include <errno.h>
 #include <png.h>
 
+#undef jmpbuf
+

  
Can you try that change and report whether cairo functions correctly
afterwards? Thanks.
