OK - since you asked...
It didn't compile on my SuSE system. It said:
gcc -Wall -c v8.c
gcc -Wall -c engine_main.c
gcc -Wall -c engine_textparser.c
gcc -Wall -c engine_roominit.c
gcc -Wall -c gui_main.c
gcc -Wall -c gui_scroll.c
gcc -Wall -c gui_menus.c
gcc -Wall -c gui_io.c
gcc -Wall -c png.c
gcc -Wall -o v8 v8.o engine_main.o engine_textparser.o engine_roominit.o gui_main.o

I've seen this before though - libpng relies on libz for doing it's
decompression - some distro's (or maybe some versions of libpng) seem
to have libpng linked *without* libz - some link it implicitly.
Adding a -lz to the link line (just after -lpng) fixes that and won't
cause problems on systems where -lpng by itself is enough.
So, now I have it compiled. But when I run the resulting binary, I get:
svgalib: Cannot get I/O permissions.
I tried running as root and I got an utterly screwed up full-screen of
random-looking garbage. When I managed to fight my way back into X again,
it had died with:
[svgalib: allocated virtual console #8]
I tried running it from a stand-alone console (ie No 'X') - but got the
same random garbage.
I'm using a GeForce-3 Ti 500 graphics card (stop drooling :-) I doubt
libsvga works very well with modern cards like that. It's been years
since I last saw a libsvga game. I really think you should use some other
graphics lib - libsvga is pretty obsolete library these days. How hard
would it be to make your game use either X or something like ClanLib,
Hermes or even SDL? It looks like you are only blitting rectangles - so
it ought to be fairly easy to port.
