>Description:
Compiling this gives an ICE:

int x;
typedef X = x;

According to this comment in c-decl.c this should be legal:
        /* typedef foo = bar  means give foo the same type as bar.
           We haven't parsed bar yet, so `finish_decl' will fix that up.
           Any other case of an initialization in a TYPE_DECL is an error.  */

Here's the complete ICE:
gcc -c typedef.c
typedef.c:2: Internal compiler error in make_decl_rtl, at varasm.c:839
