Definitely. It's weird, though, that I'm not seeing this problem. Is it because I'm building on Linux? Why didn't some test box we have fail as well?
I was able to fix it with:exclude_file_name_regexp--sc_prohibit_empty_first_line = \ - ^(README|daemon/THREADS\.txt|src/esx/README|docs/library.xen|tests/vmwareverdata/fusion-5.0.3.txt)$$ + ^(README|daemon/THREADS\.txt|src/esx/README|docs/library.xen|tests/vmwareverdata/fusion-5.0.3.txt|tools/.*\.ico)$$Not quite consistent with other places where we ignore image files; for example: exclude_file_name_regexp--sc_trailing_blank = \ (/qemuhelpdata/|\.(fig|gif|ico|png)$$) but my thoughts are that we should really ditch those one-off exception lists for graphic binary files, and instead modify this list: VC_LIST_ALWAYS_EXCLUDE_REGEX = \ (^(HACKING|docs/(news\.html\.in|.*\.patch))|\.po)$$
And this looks like the right way to go. It would deal with possible future problems as well. After figuring out the parentheses, I can ACK this to go in if you want. I'm hoping to get to cleaning up the excludes one day. Martin
