I have the local hack , and used it to find all the drivers that use a
32-bit time_t internally (and mark them with a Kconfig dependency
for testing).
Would it be ok to have a simple way of removing the time_t definition (e.g.
by passing '-DREQUIRE_TIME64' to the compiler, but without the Kconfig
option? That way, someone who wants to ship a product can at least
find the obvious dependencies on stuff that remains broken.
