That's odd, for two reasons. First, 64-bit and 32-bit mingw shouldn't 
differ, as they both use uint_fast64_t which should be the same width on 
both platforms. Second, I could not reproduce the problem on 64-bit 
Ubuntu x86-64 (after altering tempname.c to always define 
HAS_CLOCK_ENTROPY to false) test-tempname always succeeded in 10000 tries.

Could you investigate further why mingw 64-bit fails?
