Addresses: filesys.ts

uintmax_t is specified to hold at least 64 bit. This is not enough for sizes beyond 4 [sic] exabytes.

Specify whether an implementation must provide a uintmax_t that can hold the maximum possible space and file size values.

[2014-02-06: Jeffery Yasskin points out 64-bits unsigned actually has a maximum value of "16 exabytes, not 4"]

[2014-02-07: Beman Dawes suggests: This should be NAD. Such ultra-large files are the province of enterprise-wide filesystems such as requested by IBM and others for a follow-on SG3 TS. That would be the best vehicle to address this concern IMO.]
