Build feedback filtered by a script which filters out -Dthis -Wthat:
gcc -g -I../include -I../lib/lua-/src -c ../win/share/tilemap.c
The second -I is obsolete or else its bogus value would have caused
build failure. When removing it, I noticed that there was still quite
a bit of obsolete yacc and lex stuff in there. Remove that too.
