Unfortunately you haven't sent us a file named nualgol.y, so it won't
be easy for us to reproduce the problem.
I found the m4 files in the bison source direct y, but there is no
m4sugar.m4 there is no sugar anything.
This sounds like Bison wasn't installed correctly in your machine.
For example, if you installed Bison 2.0a by running the commands
"configure; make; make install" then you should be running the command
"/usr/local/bin/bison" and you should observe something like the
following behavior when you are running the shell:
$ type bison
bison is /usr/local/bin/bison
$ find /usr/local/share/bison -name '*m4sugar*' -print
/usr/local/share/bison/m4sugar
/usr/local/share/bison/m4sugar/m4sugar.m4
If you get different behavior, then your Bison wasn't installed
correctly, and that is what you need to be looking at.
make install ... would mangle
my file system. not only would it maxed out the portion, it would
overwrite datafiles.
Please install into some other area, then. For example:
$ configure --prefix=/my/location
$ make
$ make install
This will install into /my/location/bin/bison, etc., rather than
/usr/local/bin/bison. You can then repair things later by removing
/my/location.
I start with algol.y and algol.l
bison -v -d algol.y
rename algol.tab.h algol.h
flex algol.l
compile and link.
I cannot reproduce the problem with the code that you submitted. Can
you please resubmit exactly what you have now, using a gzipped tar
file as before? Apparently you've made some changes. Here's my
attempt to reproduce it:
bash-2.05a$ bison -v -d algol.y
bash-2.05a$ mv algol.tab.h algol.h
bash-2.05a$ flex algol.l

gcc -g -c lex.yy.c
