Subject: New r.mapcalc bug in G5pre4

Platform: GNU/Linux/i386
grass obtained from: Mirror of Trento site
grass binary for platform: Compiled from Sources
GRASS Version: 5.0pre4

The new version of r.mapcalc as shipped with the 5pre4sources doesn't cope with
equations like '1900.54 = if (("1900.32" > 8.0),"1900.32",0' or
'x = (1.0 + (0.3 * "y"))'

The problem seems to be the handling of the ""-terms.
Remigrating back to 5pre3 can be used as a workaround.

This looks like a similar problem that we have with the new r.mapcalc - in our
case the problem was
spaces. It appears that the new r.mapcalc has some changes in how it interprets
the expression which
is breaking old scripts - I think that it should be fixed (or reverted to pre3
version?- what else is different compared to pre3?
