 While building the Boost inspect tool from trunk (r56576) , I noticed two
 warnings from the Boost Regex library:

 {{{
 ./../../libs/regex/src/../src/fileiter.cpp: In member function
  ‘void boost::re_detail::mapfile::lock(char**) const’:
 ../../../libs/regex/src/../src/fileiter.cpp:263: warning: ignoring
  return value of ‘size_t fread(void*, size_t, size_t, FILE*)’,
  declared with attribute warn_unused_result
 ../../../libs/regex/src/../src/fileiter.cpp:265: warning: ignoring
  return value of ‘size_t fread(void*, size_t, size_t, FILE*)’,
  declared with attribute warn_unused_result
 }}}

 Here is patch that does not ignore fread and fseek return values.
