This was never addressed. Moreover, the current code is in fact broken;
OSNAME is not defined within distextract=E2=80=99s Makefile, only the =
parent=E2=80=99s,
so opt_osname.h ends up with #define OSNAME "" in it. I guess I=E2=80=99m =
the
first to notice that the top left of the screen says " Installer"
during 14.0=E2=80=99s distextract.

I am therefore once again asking for this commit to be reverted, but
this time because it doesn=E2=80=99t work, not just because I disagree =
with the
design.
