Hi, After writing an Autoconf macro that determines whether to build plug-ins with gcc or g++ [0], I realized that nested functions, which my plug-in uses extensively, are not supported in C++. Any suggestions on how to address this? Thanks, Ludo’. [0] https://gforge.inria.fr/scm/viewvc.php/trunk/m4/gcc.m4?root=starpu&r1=6090&r2=6195
