But here's the thing: when configure doesn't find lex or flex, it
sets the value of the program to ":". wth? Wouldn't "false" be
a far more effective substitute? If there's a way to tell configure
to change that behavior, we should consider it.
This behavior is part of autoconf. From the documentation for AC_PROG_LEX:
...
Fixing this for the general case would be a bit of a pain; I'm not
sure there's a wonderful answer. We could do something like outputting
a warning in configure if LEX equals ':' warning that you will need that
tool if you are building from a repository checkout, but that presumes
that people would actually read such a message :-)
Okay. You convinced me. :-)
