...

I did try it and had problems again as I said in my other post.

...

I suspect bison might be the culprit - it seems I cannot find the required version (I can only find 1.25).

Well, I had exactly this problem the other day, and when I changed parse.y, and then changed it back, everything worked, and Peter said that it was the fault of an out-of-date file that now bison was forced to recompile (or something like that).

Try 'touch'ing parse.c and parse.y, so that the two of them both get recompiled. Maybe that will help.

I did do that, and it seems that the compilation is proceeding now.... It did proceed further, but it failed with a different error now: This is the output. make[1]: Entering directory `/export/home/local/src/GNU/gcc-2.8.1/p/rts' echo 'VARLIST="PROG1"' > gnuvers.conf
