About dynamic configure options.

[Eduardo Costa]

Hi,

Is it possible at all to have a configure option whose help message can expand a
variable, or can otherwise accept the output of a command at configure-time?

For example, imagine this as part of the output of `./configure':

--with-user=user        Who to complain to (default X)

Where X could be, say, the output of the command `whoami'.

This might be done by usual means (couldn't do it) or just with some
trickery to to inject the string manually at the end of some section
(say HELP_CANON or other), and giving the output of the command on a
new line, so it doesn't get inside the `cat << LABEL ... LABEL'
constructs that seem to be used to output options and help messages.

Thanks,
