This worked for me. I deleted bison, lex, and flex from /usr/bin and
then built flex:
sed -i -e '/test-bison/d' tests/Makefile.in
./configure --prefix=/usr \
--docdir=/usr/share/doc/flex-2.5.37
make
make check
make install
...
All the checks that are run pass. There are 3 bison related tests
suppressed and I had already commented out two of them due to errors.
Then for bison:
./configure --prefix=/usr
make
make check
was clean.
What we've done here is drop a patch and replace it with a sed for flex,
and move flex up to just before bison. I think that cleans up all issues.
