 When you build gcc, you are to use `make bootstrap`; not just `make'.
 The c++ of gcc uses some gcc extensions, you are supposed to make g++ 
 without using gcc.
 
 Thanks,
 Andrew Pinski
 
 PS Also use a separate build directory.

"cp/pt.c", line 8370.9: 1506-226 (S) The ":" operator is not allowed between "void" and "unsigned int:1".
make: 1254-004 The error code from the last command is 1.

In the AIX 'C' compiler SET_BINFO_MARKED(NODE) assumes a reurn type of void.  The ternary is returning unsigned int.

cast the assignment to void.  This repairs many files where this macro is used.
