https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69197 --- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note the referenced failure looks like it can be fixed by using -std=gnu89 as part of the CFLAGS. That is it gcc 2.95 uses GNU 89 style inline which is incompatible with C99 inline.
