Are the array semantics in C++ identical to those of C, including user
defined types?

The following program compiles and executes correctly with g++
(2.3.2); but when compiling with cfront (SUN SPARC, Release
version SC2.0.1), cfront gives following error:

   "bar.C", line 21: error: address of  numeric constant
   Compilation failed
