- Add extern modifier to some declarations in header file and move qpim_all_pim_routers_addr definition to pimd/pimd.c `GCC now defaults to -fno-common. As a result, global variable accesses are more efficient on various targets. In C, global variables with multiple tentative definitions now result in linker errors.` Taken from https://gcc.gnu.org/gcc-10/changes.html Signed-off-by: Tomas Korbar <tkorbar@redhat.com>
