Fix fc-prototypes usage with C_INT64_T and non LP64 Targets.
Commit Message
The problem here is we were outputing long_long instead of
"long long". This was just an oversight and a missing check.
Committed as obvious after a bootstrap/test on x86_64-linux-gnu.
gcc/fortran/ChangeLog:
* dump-parse-tree.cc (get_c_type_name): Fix "long_long"
type name to be "long long". Add a comment on why adding
2 to the name too.

Thanks!
I think this one is obvious enough that it deserves a backport.
I've cherry-picked this for gcc12, will do gcc11 tomorrow.
Best regards

The patch is incomplete.
module foo
use, intrinsic :: iso_c_binding
implicit none
public :: bar
type, bind(c) :: bar
real(10) a
end type
end module
This yields
typedef struct bar {
long_double a /* WARNING: Converting 'REAL(10)' to interoperable type */;
} bar;
That should be 'long double'.

Fixed as obvious in 69044e11ac5 .
I will backport soon.
Thanks for the heads-up!
