I tried to use bison to make perl, only to find out that there are a 
few basic misunderstandings between Bison, Configure and Me.

It appears that selecting 'bison' instead of 'yacc' only changes the
commands
    yacc -d perl.y
    mv y.tab.c perl.c
    mv y.tab.h perly.h
to
    bison -d perl.y
    mv y.tab.c perl.c
    mv y.tab.h perly.h

However, my version of Bison does not generate y.tab.[ch], but generates
perl.tab.[ch] files instead.
After changing perl.tab.c to perl.c and perl.tab.h to perly.h, perl.c
compiles, but I get compilation errors in toke.c:

    gcc -c -fpcc-struct-return -O  toke.c
    toke.c: In function yylex:
    toke.c:186: `yylval' undeclared (first use this function)
    toke.c: In function scanpat:
    toke.c:1316: `yylval' undeclared (first use this function)
    toke.c: In function scansubst:
    toke.c:1424: `yylval' undeclared (first use this function)
    toke.c: In function scantrans:
    toke.c:1603: `yylval' undeclared (first use this function)
    toke.c: In function scanstr:
    toke.c:1651: `yylval' undeclared (first use this function)

Back to yacc again ....
