>Description:

When calling cpp as "cpp -traditional -dD", it is supposed to output
both the #defines and the result of the precprocessing.  However, with
these options cpp outputs only the #defines and does not output the
result of the preprocessing.  (The option combination "cpp -dD"
(without the "-traditional") works fine.)

>How-To-Repeat:

>Fix:

A work around is to run cpp twice, once as "cpp -traditional -dD" to
get the #defines in effect, and once as "cpp -traditional" to get the
result of the preprocessing.
