nixpkgs/pkgs/development/tools/parsing/alex/adapt-crazy-perl-regex-for-cpp-4.8.0.patch
Peter Simons 2b56b020c7 alex, happy: fix build for gcc 4.8.0
Alex and happy use CPP to generate some internal template files, but the code
is unprepared for the output from CPP 4.8.0, which generates LINE pragmas that
contain more information than they thought it would.
