I've added to SF also a patch for GPVAL_TERMINALS, which contains names of 
all terminals compiled-in. I guess it might be useful as well.

Example:
gnuplot> print GPVAL_TERMINALS
 cgm corel dpu414 dumb dxf eepic emf emtex epslatex epson_180dpi epson_60dpi 
epson_lx800 fig gif gpic hp2623A hp2648 hp500c hpdj hpgl hpljii hppj imagen 
jpeg latex mf mif mp nec_cp6 okidata pbm pcl5 pdfcairo png pngcairo 
postscript pslatex pstex pstricks qms regis starc svg tandy_60dpi tek40xx 
tek410x texdraw tgif tkcanvas tpic unknown vttek wxt x11 xlib

gnuplot> print strstrt(GPVAL_TERMINALS, " png ")
208
