 that GRASS module requires `GISRC` to be set. I'm just not sure why it is
 expected by `​g.mkfontcap` (probably it calls some GRASS library
 functions).

 the discussion about a g.mkfontcap outside a winGRASS session dates back
 to 2010.

 I've found following in this long discussion:

 Just to note, the Linux install script (binaryInstall.src) runs
 g.mkfontcap outside of a GRASS session by simply setting GISRC to a junk
 value:

 GISBASE="$DESTDIR" GISRC=junk
 LD_LIBRARY_PATH_VAR="${DESTDIR}/lib:$LD_LIBRARY_PATH_VAR"
 "${DESTDIR}/bin/g.mkfontcap" -o

 (In Windows the equivalent would be to run the command
 set GISRC=junk
 before running g.mkfontcap)
 Not 100% sure if that's relevant here, but thought it might be worth
 mentioning to give some context.

 should we try this solution in winGRASS7.x-series?
