If I may ask, which Landsat products do you use? TM5 or ETM+ 7 (pre- or 
post-2003 for the latter)?

No need to do so.

There were some issues but they are all fixed as far as I can tell (thanks to 
Jorge Tizado).  I have tested myself the most recent versions of 
i.landsat.toar (under Linux, for grass64 and grass70) and they work(ed) with 
both the old and the new metadata files that come along with the Landsat bands.

I guess so.

So the actual question, if I don't miss anything, is:  how to get the most 
recent version of i.landsat.toar compiled and running for Windows (7, 64-bit)?

Here are "latest" binaries provided by Martin Landa: 
<http://wingrass.fsv.cvut.cz/grass64/>.  This should be sufficient.

If not, here is a pointer to compile all the stuff from scratch (although I 
haven't compiled GRASS for Windows so far):
<http://trac.osgeo.org/grass/wiki/CompileOnWindows>.

Note, you can get the latest SVN source code version -- it's described in the 
sub-section:  "GRASS 6.4.svn (releasebranch_64)".

Hope this helps you.  If it is too much for you (compiling the staff from 
scratch) then maybe someone has already done that and can assist?

Best, Nikos
