Just for the reference.
IBM XLF compiler supports such syntax in component initialization as in the following code, but not the original one in the PR description I posted.
```
type dt
  integer :: int1 /2**2/
  integer :: int2 = 2**2
  integer :: int3 /2/
end type
type(dt) :: d1
print*, d1%int1
print*, d1%int2
print*, d1%int3
end
```
It seems neither gfortran nor ifx supports it.
