Seems like the message list misses a lot of errors.
I just did a "mymake > log.txt" from a cmd window.
In Build I did "type log.txt".
Then using next-error and prev-error I can step through the many many errors.
I configured Project->Tools ->Execute to be "type log.txt".
#1: Doing a "type" this way is *far* slower that doing "type log.txt" directly in the build window.
#2: After it completed, there were just 3 messages in the Message list.
What happened to the rest of the errors?
I was hoping to use MessageList as a more structured way to walk through a ton of error messages - as it filters out all the rest of the crud in the log, and lets me sort in various ways.
