<pre wrap="">I suggested before to check the compiler and linker flags which are
actually used.
Now I decided to check how to actually make the checks.
According to man gcc:
-v (verbose mode) reports the final form of the include path.
--help -v reports extra information which can be helpful.
I found that for example:
gcc --help -v 2>&1 | less
when run under Linux (Debian Lenny), displays - among lots of other
information - the flags passed
to /usr/lib/gcc/i486-linux-gnu/4.3.2/collect2 (my gcc version is 4.3.2).
DISCLAIMER:
I did not check the above when invoked by makefiles with custom
compile-time flags. Therefore, YMMV.

Look, I really appreciate everyone trying to help, but it gets a bit
frustrating to repeat.<br>
<br>
The files that are different are different after I manually (so any
question about compiler flags created by the make system are
irrelevant) feeding the two compiler an identical output produced by
gcc -E (so any question about file system paths is irrelevant).<br>
<br>
Again, thank you for trying to help, but lets try to move forward.<br>

The newlib libraries built are compared, and are identical
down to the last assembly instruction. The client libraries
are compared. Some are identical, some are not.
Just to dot all the i's and cross all the t's: are the
cross-binutils identical?

<pre wrap="">As listed in the table that started the thread, they are compiled as
part of the compiler bring up. In other words, yes.
