Additional fix for 32-bit systems.

[mr-c]

Thank you for a476126 ; I had to add the contents of this PR as well to fix the 32-bit builds of Phylonium for Debian.

Possibly this was also needed because we define -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_TIME_BITS=64 on armel/armhf?

Thanks for your continued effort on this. Could you give me the error you get on arm? I was certain that with my change it should have been fixed.

Ah, so I think the problem here is the following. On 32bit systems saidx64_t is bigger than size_t. Hence the shift is larger than the underlying type and produces a warning. (Not sure why debian gets a build failure without seeing the error. I hope they don't compile with -Werror?) The better fix would be to shift left depending on min(sizeof(size_t), sizeof(saidx64_t)).

Then there is also the more subtle issue of trying to read a sequence that doesn't fit into memory/size_t. Not sure what is the best way to prevent that.

Hi, I've pushed my version of a fix. Could you check if that solves it the Debian side?

@kloetzl f1463b7 ? Okay, I'll do a test later this weekend, thanks!
