proof of concept patch for gdc10
The attached proof of concept patch for GDC10 fixes the problem in a much less
invasive way. The idea is to just use weak attributes for global variables in
druntime instead of enclosing them in a "template {}" block.
A preliminary pull request for upstream druntime is tracked here:
https://github.com/dlang/druntime/pull/3716
The same simple fix also works fine for GDC11 if we undo PR99914:
https://gist.github.com/ssvb/d8a67fb445e96f9e66d0516a3ba62475
I first tried to toggle "flag_weak_templates" in "gcc/d/lang.opt" from 1 to 0
in GDC11 instead of reverting PR99914, but the resulting toolchain was unable
to compile and link even the most simple applications due to missing symbols
from Phobos.
The part preventing undesirable removal of cmdline arguments is cherry picked
from:
