 Replying to [comment:2 glynn]:

 not any more:
 {{{

 Enable LFS globally

 Makefile cleanup

 > 7.0 has 31 uses of G_ftell() and 48 uses of G_fseek() [...]. The fact

 outside of libgis, the module priorities would seem to me to be:
  - r.in.bin
  - r.in.ascii
  - r.in.poly
  - r.in.xyz (although there it's just used for a G_percent() estimate)
  - `r3.in.ascii`
  - r.out.mat
  - v.in.dxf
