Some parameters vary between compilers on the same platform. IIRC
whether a long on a 64-bit platform is 64-bit depends on the compiler
(windows platforms leave long as 32-bit). Alignment also differs
between compilers which will translate to differnces on disk.

Then you have things like time_t which depend on the C library you use.
size_t depends on the memory model, or perhaps even on the compile
flags. integer datetimes is a configure option.

There's nothing to stop you trying, but there's been no effort in
making it work.

Have a nice day,
