Dear Adrien, thanks for your detailed answer! I will do more experiments and then send a summary and request some doc extensions/updates as you suggested below. Regrading the \r\n problem: the tr -d '\r' can be integrated into the runtest script as attached, so it would be only in one place. But for the time beeing I am using the supplied makefiles - as I said using configure was just a mistake. I did too much GTK building recently ;-) Still I got fairly far with the configure approach with just a few minor changes. Regarding flexlink/flexdll: This somehow is in the configure scripts, but it doesn't seem to work. When building with configure, the system tries to link with gcc rather than flexlink and the flexlink defined symbols are missing then. I hacked it into the makefiles to get forward. I didn't find out what exactly went wrong between configure and make. The mkexe define seems to be used in different ways.
