Thank you.

The compiler did run (I could see it in the task manager) but it was not
exiting for a minute or so. After I restarted my computer, everything
started to work as expected. (Not sure why.)

I can make my custom compiler use these kind of messages:

sourcefile:line1.column1-line2.column2: message

Here are some more questions:

* The above format cannot be used under windows, because the source
file name can have a colon in it. (E.g. C:\temp\text.txt:12:14). I
really want to use absolute file names, because the compiler that I
write is able to read source files from different drives
automatically, and because the files are organized in packages (so
two file can have the same name if they are in different packages).
How to overcome that problem?
* Unfortunately, the message can also contain a colon. What to do with
that?
* How to distinguish errors from warnings? I was reading the
[build-menu] but I could only find some examples. It was not clear
how to do it.
* Another question: can I make Geany open a file if it is not opened
yet? E.g. a file is listed in an error message, but it is not opened
in Geany yet. I would like Geany to open that file when I click or
double click the error message.

Thanks,

Laszlo
