No, because they know some parts are missing or broken.  They do
however keep a status chart of how they match up:


In one interesting case, gcc was known to not conform to a subtle
aspect of C99 having to do with the relationship between sizeof and
offsetof on a struct with a flexible array member:


Here's an example of the problem in the wild:


Apparently the WG decided that gcc (and the other compilers including
tcc) had it right because n1124 has new wording that seems to remove
the constraint the compiler(s) were violating.
