-Subject: [PATCH] bridge/vlan.c: bridge/vlan.c: fix build with gcc 14 on musl
- systems
-
-On glibc based systems the definition of 'struct timeval' is pulled in
-with inclusion of <stdlib.h> header, but on musl based systems it
-doesn't work this way.  Missing definition triggers an
-incompatible-pointer-types error with gcc 14 (warning on previous
-versions of gcc):
