Clever! But won't the compiler care if a line gets too long?

If you have a preprocessor, you will also need a binary postprocessor to edit the linenumbers. IOW the preprocessor should keep track that original.pas:21 becomes processed.pas:25, and your binary postprocessor should parse all stabs and patch these occurances. Maybe you need a few dummy units with the same names as the included ones to create entries for these units. However a binary postprocessor is a bit complicated. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
