64 bit math on ia32

Hello,

I am not sure this is a bug with glibc. I am trying to use Large File
Support with Debian Sid. I have compiled my program with the proper
defines. When I try to calculate my index as a gint64 var, it wraps at
32 bits and my file is limited to 4GB.

I would have thought that Gcc would see that I am placing the final
result into a 64 bit type and would substitute in 64bit compatible math.
Is this not the case?

If this will not work, how can I calculate a 64bit offset. I assume LFS
is not limited only to 64bit architectures?

Any help would be appreciated.

Dennis
