![]() Even with the noinline specifier added by commit 1a260f8, gcc may skip calls to non-inlinable functions that it knows have no side effects. This caused the get_cached_dhcpack() call in start_dhcp(), the weak stub of which has no code in its body, to be removed, preventing cached DHCP from working. Fix by adding a __keepme macro to compiler.h expanding to asm(""), as recommended by gcc's info page, and using it in the weak stub for get_cached_dhcpack().
