When using a C++ compiler on OS/400, a lot of files fail to compile.  (Note that my other bug reports was using a C compiler.)  Most of the failures has to do with returned pointers from emalloc, erealloc, malloc and realloc.  These functions are returning a void pointer and are not being cast to the data type of the variable receiving the pointer.  I hope that this can be changed.   Some of the code does cast, but most do not.
