I do not understand which of the following holds true: - The diff shows what fixinclude did. It shows the different between the original version (extracted from test-text) and the version that fixinclude produced by applying your diff. - The diff shows the mistakes of fixinclude, if any. It shows the different between what fixinclude produced as output (by applying your fix to the test-text) and what it is the expected result (which you have to put in a different file -- where? how?). >> 4.

This process can be done if you have physical access to the host with the broken header. In my case, I was developing a fixinclude for a broken header for another system. I have the broken header as a file (attacched to the bug). How can I test my fix in this situation? BTW: "rebuild the compiler" is a tad too much as first quick test for a fixinclude (e.g. check that the regulard expression does not have a typo or so). Even assuming access to the host, would you please explain if there is a quicker wasy to just run fixincludes without rebuilding everything? Of course, a full bootstrap would be still required as a final check. > That means send me email if you are still having problems.
