Re: [Bug-apl] Error compiling on Mac OS X 10.13.6

[Dr . Jürgen Sauermann]

Hi Louis,

I fixed the chdir() warning (*SVN 1142*). This empty if statement was
only included to silence another gcc warning.

I also removed the *-W-old-style-cast* warning which seems to be no
longer required (all cast should be converted
to C++ casts by now).

Thanks,
/// Jürgen
