Fix for GCC9 new OpenMP data sharing
GCC 9 started implementing the OpenMP 4.0 and later behavior. When not using default clause or when using default(shared), this makes no difference, but if using default(none), previously the choice was not specify the const qualified variables on the construct at all, or specify in firstprivate clause. In GCC 9 as well as for OpenMP 4.0 compliance, those variables need to be specified on constructs in which they are used, either in shared or in firstprivate clause. Specifying them in firstprivate clause is one way to achieve compatibility with both older GCC versions and GCC 9, another option is to drop the default(none) clause. This patch thus drops the default(none) clause. See https://gcc.gnu.org/gcc-9/porting_to.html#ompdatasharing Signed-off-by: Robert-André Mauchin <zebob.m@gmail.com>
