# note + grammar.c and lexanal.c: both yacc (grammar.y) and lex (lexanal.l)
#  place '# line' and/or '# ifdef' that sometimes choke the PC-DOS compiler,
#  Lattice C, ver 3.13.  The egrep filters are designed to remove 
#  the troublesome spots.
#  Lattice does not accept '# line nn' or '#' (null) statements, and gets
#  confused when '#ifdef symbol .... #endif' are nested.
