Verify that sections of LaTeX output that use auxiliary files (a
bibliography in our configuration below) are consistent when re-run
after modifying the input file.
This checks for a bug that was triggered by the presence of auxiliary
files which were detected by SCons but then removed prior to invoking
TeX, causing the auxiliary sections to be excluded from the output.
That was fixed (courtesy Joel B. Mohler) by making all the relevant
auxiliary files Precious().
Test configuration courtesy Dmitry Mikhin.
