+ 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).
