Use the binutils that come with FPC, not the ones from mingw. mingw's coreutils package has afaik moved in a different direction since it moved from mingw to msys.

[fpc-pascal] Permuted index (KWIC) of function descriptions
As a comparative beginner, I still find myself stumbling across RTL functions that I've previously hand-coded. Is there an easy way of generating a complete permuted index from the one-line descriptions of the functions in the RTL (and optionally FCL and LCL)?

Do these positions are different, depending on microprocessor being used ?

I'm fairly certain that is an error in the documentation, and that it
SHOULD
always be as you discovered it to actually be.
As an aside, a tip for doing pointer arithmetic...
var
s : ansistring;
p : ptruint;
p := pointer(s);
dec(p); // equivalent to p:=p-4 because p is a typed pointer.
Using typed pointers in this way will likely make it easier to adapt your
code
to a 64-bit conversion in the future.
Also note that, in this case, dec(p,2) would do p:=p-8, as (hopefully)
expected
I use these types of constructs frequently, and it makes it much easier to
change types, if that is ever necessary, or adapt constructs to new types.
Cheers,
David

I fail to see why you need to mess with the internals of ansistrings at
all.
What is the reason to access size and reference count this way?
At least for the size there is Length(cad1) which would be much clearer.
Although pointer arithmetic is possible in Pascal it looks like C.
And you loose any help from the compiler to check types.
