Comment (by anonymous):

 What about casting to void the call to fread?
 {{{#!c
 (void) fread(...)
 }}}

 This should suppress the warning without adding the extra cost to check
 the value returned by fread.

 Otherwise, there is a patch that check this value here:
 http://boost.2283326.n4.nabble.com/PATCH-1-2-Fixed-warning-ignoring-

 return-value-of-size-t-fread-void-size-t-size-t-FILE-td3145963.html
 with the disadvantage of adding another warning when suppressing the
 BOOST_ASSERT.
