- # We must build bootparse.c and bootscanner.c with yacc and lex and sed,
- # but bootstrap.c is part of the distribution.
- #
- # Another kinda weird Makefile cause we need two
- # scanner/parsers in the backend and most yaccs and lexs
- # don't have the prefix option.
- #
- # sed files are HACK CITY! - redo...
