Except for sporadic comemnts, the only lines which were comemnted out were
the following (now uncommented):

y.tab.h y.tab.cc: $(YYSRC)
 	@-$(RM) $@                    # my comment: line 43
 	$(BISON) $<
 	mv -f y.tab.c y.tab.cc

lex.yy.cc: $(LLSRC) y.tab.h
 	$(FLEX) $< | sed -e 's/^#include <unistd.h>//' > $@
 	echo '#ifdef __VMS' >> $@
 	echo '// Some versions of DEC C++ for OpenVMS set the module name
used by the' >> $@
 	echo '// librarian based on the last #line encountered.' >> $@
 	echo '#line' `cat $@ | wc -l` '"lex_yy.cc"' >> $@
 	echo '#endif' >> $@

So I guess I uncommented the right lines. (Besides they refer to the YYSRC
and LLSRC variables, so they must be the right lines.)

I have to problems now:

1) After removing the comment signs, Emacs warns me when I try to save
the changes that there is a "Suspicious line 43. Save anyway (y or n)?" I
can save the file by choosing "y" but neither make nor gmake would compile
any more. When issued in the ../cxx/ directory both commands report:
"dir.mk:43: *** missing separator.  Stop."

Should there be any "\" sign anywhere?

2) what do you mean by "remove the source files from the source tree". Do
you mean that I should remove all C and C++ files (that is all .c, .cc,
.h files)? Or just the object files or all? I hope all I need to do is
"make clean", because I am affraid I will have to make the compiler many
times.

Thanks for your help so far,
Catalin
