Bug 579039: Limit SOURCE_DATE_EPOCH to fit 32bit unsigned int

Browse source 
The impementation in GCC allows a value up to 253402300799 that
corresponds to "Dec 31 9999 23:59:59 UTC". Apparently, this is due
to some limit of __DATE__ and __TIME__ within the preprocessor.
Regardless, as the reporter claims to have problem with values
outside the range of a 32bit unsigned integer, lets use
"(1 << 32) - 1" as a limit.
