Generally, for trap and MetaPost trap, dates and times, a number of
constants and one call to BLANKRECTANGLE will be different.
-For trip, again some constants will be different. The floating point
- numbers in glue set ratios may be slightly different (but all the box
- dimensions must be the same), and the y* and down* commands in the
- trip.dvi file may be somewhat different. The hyphenation exceptions
- are different because the exception routine now does not count
- identical hyphenations separately, i.e., \hyphenation{a-a a-a} only
- generates one exception in the table. See the messages below for why
- this is a good/necessary thing (if the hyphenation exception table is
- to be dynamic at all).

texmf.cnf -- sets up various constants the way the tests want them. Not
all constants can be changed, alas, but this suffices to avoid building
