Ok. Just to clear it up completely for me: when you set that directive 
mingw does understand %lld ?

Would that also work on Windows XP or not ? Hmm, Windows XP is 32-bit 
only so perhaps when building on WinXP you never see that directive. Is 
it a problem only for 64-bit ?

Perhaps related: business users can define a number format for 
invoices/bills via File->Properties->Business. I remember there also 
this problem of %lld vs %I64d is rearing its ugly head. So if we build 
gnucash with the above directive perhaps this problem would go away as 
well ?
