>Description:
Tried to compile 2001-04-02 gcc 3.0 snapshot. Standard options: |../gcc-source/configure --enable-threads --enable-shared; make bootstrap|.

I didn't have bison installed.

configure worked, as far I as I could see, but compilation quickly (after 30 seconds or so) failed with missing files (see below). After I installed bison, it worked fine.

Last lines of make output:
(cd ../../gcc-20010402/gcc/java && \
false -t --name-prefix=java_ -o p$$.c parse.y && \
mv -f p$$.c parse.c)
make[2]: *** [../../gcc-20010402/gcc/java/parse.c] Error 1
>How-To-Repeat:
(guessed)
1. Rename the bison executable of your system.
2. Extract gcc3.0 snapshot, configure (in separate bin dir), make bootstrap.
>Fix:
(proposed)
Check for existance of bison in configure. Bail, if not found.
