Very sorry for the hassle you are having here. I am currently building
eclib on my 32-bit laptop (ubuntu 12.04) in case there are any other
32/64-bit issues. In fact I am already seeing a lot of warnings "overflow
in implicit constant conversion [-Woverflow]" from the included file
xmod.h (in line 114, i.e. where INV_BIGPRIME is defined, as you found)
which certainly needs to be fixed. Wait for me before spending more time
(though I only have another half hour today as I'll be going out shortly
-- to see Shakespeare's Comedy of Errors, so very appropriate!).
All the things you report could be explained by some overflow in low-level
arithmetic, it will not be as serious as it looks.
