 Hi,

 moving this out of the noise of #1006 so we can close that one asap.

 part of the work-around for the #1006 r.terraflow on WinGrass fix replaces
 stat() with ftell(), as stat() on Windows gives undefined results if the
 file is still open.

 The ftell() solution is not 64bit safe though, so it awaits a backport of
 G_ftell() [or even better `off_t G_filesize()`] in some later release.

 This does not affect the UNIX side of things, the ftell() is within a
 #ifdef.
