Did you use ./configure --enable-largefiles? It defaults to no for some 
reason.

32-bit x86 has increasingly poor support in Linux. Arm is still getting 
attention (Debian is trying to do a time_t 32->64 migration on 32-bit 
Arm platforms) but personally I think 32-bit server platforms are 
starting to look like retrocomputing now.

Even the embedded platforms I use in my day job are 64-bit now!
