- Subject: [doc] Remove obsolete Tru64 UNIX V4/V5.0 support
Here's the second port removal patch for Tru64 UNIX V4 and V5.0. Should
likewise be obvious and require no approval, except for the fixincludes
part where I'm removing a fix only used on alpha*-dec-osf4* which is
gone.
I've renamed t-osf4 to t-osf5 to reflect its current use, and likewise
merged osf.h into osf5.h, simplifying the latter a bit.
I'm not including removed or renamed files in the diff.
Tested by trying a bootstrap on alpha-dec-osf4.0f which fails as
expected; alpha-dec-osf5.1b bootstrap still running.
Ok for mainline if it passes?
