Is the output of the preprocessor deterministic ?

Is the output of the C preprocessor deterministic ? What I mean
by that is , given 2 compilers which conform to the same standard,
will their preprocessors produce identical output given as input
the same file ? If not then how much variation is allowed ? Is it
just a bit more or less white space here and there or could could
there be larger differences ?

If the output is not deterministic then is it possible that the output
of the preprocessor of one compiler can not be processed correctly
by another compiler ?
