According to the EULA, you may distribute anything listed in redist.txt:

"""2.2	Redistributable Code-General.   Microsoft grants you a 
nonexclusive, royalty-free right to reproduce and distribute the object 
code form of any portion of the Software listed in REDIST.TXT 
("Redistributable Code").  For general redistribution requirements for 
Redistributable Code, see Section 3.1, below."""

So the right to distribute is coupled to the a) the EULA and b) 
redist.txt. (As a side note, the Microsoft Visual C++ Toolkit 2003 for 
example contains NO redistributables per redist.txt).

In the case of not owning a compiler at all, chances seem pretty slim 
you have any rights to distribute anything.
