Sorry to spoil the party -

Does this mean, not even the ugly work-around to set 
GDFONTPATH=/dev/null to get the builtin fixed fonts of libgd
will work any more?

I really would like to have a possibility to use the builtin fonts.

The simplest thing would be to treat the libgd font names special?

I.e. if the the font name is one of 
"tiny","small","medium","large","giant" treat them special,
skip font lookup and directly use the respective libgd builtin fonts?

I.e. the use would then be as
...
set term png font "small"
...


Would be great!

Cheers,
Manfred
