Details:

Currently, PSPP rejects system files that put missing values on long string
variables.  SPSS 16, however, supports missing values on long string
variables, and it appears to do so by using the existing field for missing
values, thus PSPP needs a small fix to ignore them.

SPSS 16 also uses two new system file extension records (subtypes 20 and 21).
 We can ignore these too.

Patch sys-file-long-string-missing-values.patch takes care of these  issues.

sys-file-reader-uninitialized-data-fix.patch fixes an unrelated problem that
I noticed while reading code.

sys-dissect.patch adds a new tool "dissect-sysfile" that is useful for
figuring out why PSPP might not like a system file, or at least viewing the
system file's structure.

Comments?
