Assuming you are using VC 2005 and gd-2.0.35 . . .

I had the same problem. It had me stumped. Here is how I solved it.

Get the extras package from:

   http://www.libgd.org/releases/extras/gd_build_win32_deps.zip

Then extract it somewhere on your hard drive. Edit the makefile in
the windows directory of gd-2.0.35 and point EXRTRA_INCLUDE and
EXTRA_LIBS to where you extraced gd_build_win32_deps.zip files:

(below my example assumes I extracted to gd_deps inside gd-2.0.25)

   EXTRA_INCLUDE=C:\\gd-2.0.35\\gd_deps\\include
   EXTRA_LIBS=/libpath:C:\\gd-2.0.35\\gd_deps\\lib

Then compile libgd (nmake -f Makefile)

Copy the resulting bgd.dll & bgd.dll.manifest to your gunplot
install directory and you will be able to save to png.
