#1 '::main' must return 'int'

[Sam Wilson]

On typing 'make' I get the following error:

bison patoo3d.y
g++ -o patoo3d patoo3d.tab.c -I./libs -lm
-L/usr/X11R6/lib -lX11 -O3
patoo3d.y:249: error: '::main' must return 'int'
make: *** [patoo3d] Error 1

This looks like an interesting program; I look forward
to using it.

Thank you.
