It fails in a ports build with 2.71, and it fails with the bundled
configure script.
Seems that the problem is that ac_cv_prog_lex_root ("checking for
lex output file root... lex.yy" is set by ports infrastructure in
config.cache but that the subsequent "checking for lex library"
depends on the file created in the ac_cv_prog_lex_root check.
[...]
checking for bison... /usr/bin/yacc
checking for flex... (cached) flex
checking for lex output file root... (cached) lex.yy
checking for lex library... cat: lex.yy.c: No such file or directory

cat: lex.yy.c: No such file or directory
not found
configure: WARNING: required lex library not found; giving up on flex
checking for library containing yywrap... -lfl
[...]
This issue is fixed by one or other of the two infrastructure diffs
below. I prefer the first; the 'none needed' setting feels a bit magic.
If anyone is able to add it to a bulk I'd appreciate it (I don't expect
a problem, but since the file is used for every CONFIGURE_STYLE=gnu or
autoconf in the tree, it feels safer to test first).
