I am concerned about the `-o` option itself. As per the POSIX.1-2008
[0], lex only supports -t, -n and -v. Though agreed flex is the de
facto implementation of lex which supports `-o`, I think we should
stick to the POSIX standard and shouldn't use `-o`.

I see 2 possible approaches:
1. use lex.yy.c, default file generated or
2. use `-t >` to have the desired custom filename.
