annotate rogue4/move.c @ 164:49af2fd0bb0c
Move some autotools files to where configure can find them.
rogue5 uses config.guess and config.sub to find the canonical system
names. The configure script expects them to be in the same directory
as install-sh. So they have been relocated to the top level.
This is a quick and dirty fix. The eventual plan is to relocate them
to /dev/null.
I also suspect they should be used to set HOST, not TARGET. Rogue is
not a cross-compiler.
