gentoo-overlay/dev-libs/bglibs/files/bglibs-1.106-parallel-fix.patch

Forward port to 1.106 by Thilo Bangert <bangert@gentoo.org>
Fixes for parallel compile.

- Redirection straight to an output target that is later used for dependancies
  is not safe. The output file must be come into existence atomically.
