31 Searching bgo for "gcc" is just painful, so I added the error you posted
32 to the search string:
33
34 gcc Bootstrap comparison failure!
35
36 Often times the searchstring makes all the difference and searchstrings
37 are an advanced technology therefore indistinguishable from magic. If
38 they were easy and not magic-like, they would be insufficiently advanced
39 for our needs (with apologies to a certain mr Clarke)
