>Description:
The bootstrap target in src/usr.bin/lex/Makefile (meant to build lex on a lex-less system) is broken. It generates scan.c but not parse.h which is also needed.
>How-To-Repeat:
Remove (or rename) /usr/bin/lex and, in src/usr.bin/lex, try:
  make bootstrap ; make

>Fix:

Copy the dynamicaly generated parse.h into initparse.h, then apply this to Makefile:
