To clarify this, a PDS is the analogue of an uncompressed tarball,
and is the usual way of storing source-code files on MVS, not only
for transport but at all times, because the number of files that
can be stored on an MVS volume is quite small.  The MVS file system
is not hierarchical, so there is no concept of a working directory
(or of a directory at all, really).

Furthermore, files cannot be created without providing detailed
parameters, so it is normal to indirect all file accesses through
the DD statements, which are like special-purpose environment variables.

Which is equivalent to hacking the gcc tarball in order to compile
this program.  Not to mention changing the mapping table that maps
"sys/types.h" to TYPES.
