It's a pitfall of C90 - any integer type larger than long is not
supported.  FYI, this also spells doom for large file support, too.

What minimal coding standards does GRASS conform to?  ANSI C (C89-C90)?
Unless there is a quick workaround, is there any reason for not
supporting C99?

By the looks of the vector library, it'll be difficult to fix because
they are fed to read()/write().  Perhaps it could be poorly fixed by
reading and writing two ints and splitting it into upper and lower
dwords.

My $0.02 (and falling)

Glynn?
