Follow-up Comment #3, bug #51990 (project lwip):

mpu_lwip_select_master.patch isn't building on MSVC:


1>e:\projects\lwip\src\api\sockets.c(217): error C2011: 'lwip_select_cb' :
'struct' type redefinition
1>          e:\projects\lwip\src\include\lwip\priv\sockets_priv.h(145) : see
declaration of 'lwip_select_cb'


Also, there are some return cases in lwip_select() that aren't calling
'API_SELECT_CB_VAR_FREE(select_cb);' these are new cases from what's on
STABLE_2_0_0
