Why, if you don't mind me asking? I'm not using any wimp calls ATM (that
comes later...).

Thanks for confirming that.

Philip, thanks very much -- the light is dawning. I'm obviously a bit
unclear on how all the tools join together; and was assuming that once
you'd specified a library the rest was automatic.

Anyway, it works now, and many thanks!

Well, apart from running into a 'Command line too long' error from the
front end, although it compiles and runs OK. It looks like I'm running
into the limitations of the front end, and will indeed have to start on
Make files, which I suspect will clear up such problems.

Yes, it was the linking step that was the problem.

One problem I've already run across is that there appears to be a number
of incompatible formats of makefiles, all with the same filetype....

Thanks again for the help -- much appreciated.

Best, Chris
