Impossible to turn off character/text anti-aliasing for gif (GD)

[havatv]

With 6.0.0, it is not possible to turn off text anti-aliasing for gif (GD) using "ANTIALIAS false". It is neither for truetype symbols nor for labels. This was possible in 5.6.6.

Here is a map file that can be used to demonstrate the bug (FONTSET will probably have to be modified). I attach the resulting images generated using 5.6.6 and 6.0.0.
