 Hmph. The ticket is however not a blocker ;-)

 6.5 already and just need a backport.

 it's an embarrassment not to have them working properly (even if their
 full glory is crippled as in the case of LFS + r.terraflow).

 Its flagship character comes from its ability to process very large
 datasets, but all its functionality including the ability to process large
 datasets is also covered by other modules. Without LFS, r.terraflow is
 limited to less than 27 million non-NULL cells, converting the module from
 a flagship to a dinghy. I am very much inclined to change milestone to 7.0
 and set priority to normal.

 Tested 6.5svn r42716 on XP, same error as in comment:29 in filldepr.cc.
 Once that is fixed, we might have a look at why r.terraflow refuses to run
 with output from r.volcano... No, seriously, r.terraflow and iostream is
 written for Linux, as also previous tickets have shown, no reason to
 expect that this is the last problem with Windows. Please leave it for 6.5
 or 7.0.
