I've tried to build the new tools for CentOS 6 / Scientific Linux 6 /
RHEL 6 etc.

During the build process, I see:
cmds-fi-du.c: In function 'du_calc_file_space':

this function)
cmds-fi-du.c:330: error: (Each undeclared identifier is reported only once

make: *** [cmds-fi-du.o] Error 1

I'm guessing this is probably due to a different GCC version used? I'm
guessing this is a simple fix for someone with knowhow... :)

This is due to too-old headers.  That define was added in 2.6.33.

#define FIEMAP_EXTENT_SHARED            0x00002000 /* Space shared with other
                                                    * files. */

Just add that above that routine and you'll be good to go.  The right fix
is to add it to the tools, ofc.
