https://svn.boost.org/trac10/ticket/2454 <p> I am seeing a far number of what MS regard as level 1 (most severe) warnings from various fusion files, for example: </p> <p> i:\trunk\boost/fusion/iterator/next.hpp(60) : warning C4180: qualifier applied to function type has no meaning; ignored i:\trunk\boost/fusion/sequence/intrinsic/begin.hpp(64) : warning C4180: qualifier applied to function type has no meaning; ignored i:\trunk\boost/fusion/sequence/intrinsic/begin.hpp(71) : warning C4180: qualifier applied to function type has no meaning; ignored i:\trunk\boost/fusion/sequence/intrinsic/end.hpp(64) : warning C4180: qualifier applied to function type has no meaning; ignored i:\trunk\boost/fusion/sequence/intrinsic/end.hpp(71) : warning C4180: qualifier applied to function type has no meaning; ignored i:\trunk\boost/fusion/iterator/prior.hpp(60) : warning C4180: qualifier applied to function type has no meaning; ignored </p> <p> I doubt if it is worth changing/correcting the code, but users will be justifiably alarmed, especially if, as in my case, I am not explicitly using Fusion! </p> <p> However I am unclear how best to suppress these warnings, short of a lot of push'n'pop pragmas into a lot of files. Is this not a problem on gcc? </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/2454 Trac 1.4.3 Paul A.
