+    This error crops up when a build system mixes system headers (say glibc) 
+    with the target headers (say uClibc).  Make sure your build system is not 
+    including extraneous include options (-I) and double check that it is using 
+    the correct compiler.  Many build systems incorrectly force things like 
+    -I/usr/include or -I/usr/local/include or -I${prefix}/include (which usually 
+    just expands to -I/usr/include).
