timev.h: just use "unsigned int" for bitfields

Browse source 
There's no point in having separate types depending on C dialect
when using bitfields, "unsigned int" bitfields are bitfields
anywhere.

Note: we also have test_memsize in test_time.rb in case
users of other platforms want to enable size assertions
if they don't trust their compiler.
