Patch to not to ignore fread and fseek return value

[mloskot <mateusz@…>]

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.

I've forgotten to add environment details:

• I'm using GCC 4.3.3 on Linux Ubuntu 9.04 (Intel 64-bit)

Fixed in Trunk. Thanks, John.
