<p class="MsoNormal"><span lang="EN-US">It appears that two system include files, mathcalls.h (default OS) and cmath (from RH DevToolKit) both have definitions of functions "isnan", and OSG's Math header uses it in an ambiguous manner.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Any idea about how to fix this?<o:p></o:p></span></p>
