[Patch, Fortran, OOP] PR 49112: [4.6/4.7 Regression] Missing type-bound procedure, "duplicate save" warnings and internal compiler error

[Janus Weil]

Hi all,

while I continue working on some of the yet unsolved parts of this PR,
I'm already posting a simple patch which fixes the part with
"duplicate save" warnings on CLASS variables (which is a regression on
4.6 and trunk). The warnings are silenced by making the vtab and
default initialization symbols SAVE_IMPLICIT (right now they falsely
are SAVE_EXPLICIT). This is a pretty obvious fix, and rather safe to
apply to trunk, I think.

However, I would also like to apply it to the 4.6 branch (which was
frozen a few hours ago). Is there any chance to get approval by the
RM's for this?

In any case, the patch was regtested on x86_64-unknown-linux-gnu. I'll
commit to trunk as obvious tomorrow.

Cheers,
Janus
