Description Mike Cvet 2007-04-25 18:09:31 UTC 
Occasionally after a rebuild from scratch with a make -j3, I come across the 
following build error which dissapears after another make right afterwards:

Comment 1 Andrew Cagney 2007-04-30 21:10:13 UTC 
Likely the file is making an indirect instead of explicit include of a generated
header leading to a race between the header's generation and its inclusion. 
Check that all relevant headers are explicitly included by that file.
