Would Expand(100u) work here and elsewhere ?

[miu, 2015/12/10 00:38:36]

Yes, but the interpretation of 100u would be different when using different
compilers/platforms (i.e., is it a 32-bit unsigned int, or a 64-bit one?). 
IIRC, there was a past discussion on chromium-dev@ encouraging us to use the
cross-platform macros (e.g., UINT32_C() and friends) rather than 100u.
