Re: gnubol: Problem 10 => message API

[Tim Josling <tej@melbpc.org.au>]

You can store the messages and sort by line number later. This
would be difficult with the separate preprocessor for
preprocessor error messages.

Anyone want to write a message API?

- manage whether certain message numbers and severities are to be
output and/or counted and/or used to decide success
- sort by line number
- print
- maybe provide a basic printf type facility for building the
strings.
