Comment (by jinmei):

 What's the right way to run scan-build?

 I've downloaded and extracted http://bit.ly/13ekSoV
 from http://clang-analyzer.llvm.org/installation.html

 and do this on the `bind10` directory of the latest master (9b16b11):

 {{{
 % <path-to-scan-build>/scan-build ./configure ...
 % <path-to-scan-build>/scan-build make
 }}}

 but at the end of build it said:
 {{{
 scan-build: Removing directory '/tmp/scan-build-2013-02-08-1' because it
 contains no reports.
 }}}

 And there seemed to be no output.
