Also my initial claim about c++20 was wrong, gcc 10+ generates the error when
provided with -std=c++2a switch.
Still there is a problem in c++17 mode.

Also shorten some text, call GCC that instead of GNU GCC compiler,
and remove some bits and links where there appears no equivalent

Hi,
this is patch I am using to fix the assumed_alias_type.f90 failure by
simply arranging alias set 0 for the problematic array descriptor.
I am not sure this is the best option, but I suppose it is better than
setting all array descritors to have same canonical type (as done by
LTO)?
