Rip out AIX, Tru64, Solaris, Irix support
All these OSes are long obsolete, avoid cluttering the source.
-
__osf__
is Tru64 -
__svr4__
(System-V Rel 4) distinguishes between Solaris and SunOS
The test for TIOCSCTTY
can be dropped as obviously KDE_open
is never
used, it requires kde_file.h
from kdelibs4support.
The test for _POSIX_VERSION
can be dropped as unistd.h
always defines
_POSIX_VERSION
and is included unconditionally.
