The first stage of GCC can in general be built with any compiler.
That is how you build GCC the first time on a machine where no
previous versions of GCC are available.  Stage 2 then rebuilds GCC
with itself.

I haven't tried to build with MSVC, so I don't know whether it is
practically possible, but it isn't inconceivable.

You forget the system- and compiler-specific #ifdef's.  So no, it's
not the same source.

That depends on how GCC is configured, and what Binutils does it use.
These are the two factors which define the output format.  Recall that
GCC just generates assembly, it relies on an assembler to produce
machine code in the appropriate object format.

Again, this is theory.  I have never done that myself with MSVC
(neither will I try, if it depends on me ;-).
