We intend to remove it anyway as r.in.gdal should do the job.
Please report cases (with data) where r.in.gdal fails to the
GDAL bugtracker.
Do we know if and when Frank is going to fix that GDAL takes the floating point AI ASCII GRID as an integer if there is more than 1K of null values, ususally represented as "-something", in the beginning of such an FP grid?
Besides - would r.in.gdal recognize if the grid is DCEL or FCELL? Or is there a way to force either like in r.in.arc?

Nobody answers so I assume that we don't know. In that case removing
r.in.arc makes no sense yet - until this bug in gdal is fixed. Otherwise
ther will be problems an bug reports from people having nulls in the
beginning or their grids, which is not that unlikely to happen.

So I assume that r.in.gdal doesn't let one to recognize or force the
required accuracy. Another reason for not removing r.in.arc yet.
What do you think?

IMHO this message should be posted to the GDAL mailing list as
it belongs to GDAL. Please post there as well.

Maybe related flags could be added to r.in.gdal to enforce CELL/FCELL/DCELL.

I suggest to keep r.in.arc in GRASS5.7/6.0 until this is fixed in r.in.gdal,
Maciek, please post to GDAL list because it needs to be fixed in GDAL.
