Hi Glynn, 

thanks for your comments.

I'll check this another time.

Problem is on cygwin:
my configure line:
./configure --prefix=$INST --with-postgres-root=/usr \
--with-postgres-includes=/usr/include/postgresql \
--with-postgres-libs=/usr/lib \
--x-includes=/usr/X11R6/include \
--x-libraries=/usr/X11R6/lib \
--with-tcltk-libs=/usr/local/lib \
--with-tcltk-includes=/usr/local/include \
--with-gd-libs=/usr/local/lib \
--with-gd-includes=/usr/local/include \
--with-png-libs=/lib \
--with-png-includes=/usr/local/include 

sinppet from config.log:

First, why is gdImageGif checked? GIF support was officially dropped in
gd some time ago. 
The gdImagePng(); test fails, even if i manually compile a test program.
But the test programs from gd-1.8.4 all compile. I have at the moment no
time to investigate further.


Now i re-run configure on Linux and the gd library is not found, too:
