You guessed right: my target arch has 32 bit instructions (which I 
expressed with base-insn-bitsize == 32), and uses 64-bit words for data 
and addresses (expressed with word-bitsize == 64).

Good to hear, thanks!

I found the cast could be fixed by changing the "(dfm 'DI..." line in 
mode.scm, but have no idea about the possible side effects, and didn't 
find a cure for the use of long anyway.
