Thank for your reply. I also think it is not need to set GS_LIB 
now. GS_LIB is used only in pstoimg.pin to set the environment 
variable GS_LIB, which was needed by some version of old 
ghostscript. Recent versions of gs know correct library path,
and the setting of GS_LIB manually may disturb the running of gs.
So the detection routine of gs lib and font path in config.pl may
not be need.

Instead, it may be need to detect the validity of png16 device of
gs, which is used in current latex2html.
