I see the variable filetype initialized to 0 in loadfile.c and there's a comment there saying that when 0 its for GIF files. Later in framain2.c, there's a comparison suggesting that values >= 1 are "old .tga format input file", where outline is assigned to outline16. Later, there's another check on this variable changing the argument to funny_glasses_call, with either gifview (filetype = 0) or tgaview (filetype != 0). However, there is nowhere in the code (.c or .asm) where filetype is assigned a value larger than 1. Is this dead code? This is the only place that tgaview appears to be refenced.
find "filetype" common\*.c dos\*.c dos\*.asm headers\*.h
