`CString' handling has been significantly improved since the days of
gpc-2.0.  Please take part in beta-testing gpc-970624, available at
ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/beta/.

It's needed for compatibility with C, Borland Pascal, and Delphi.
(For the latter cases it can also be called `PChar' now.)  And, BTW,
in gpc-970624 you can drop the underscores.
