Yes. It still is a type violation, even if it will work in most cases. Just for the record, before working on GCC, I wrote the front end of a C compiler for a machine (Data General MV/Eclipse) that had different types of pointers, and it was definately a hassle, particularly in the era before prototypes were added to the language. -- Michael Meissner, IBM 4 Technology Place Drive, MS 2203A, Westford, MA, 01886, USA meiss...@linux.vnet.ibm.com
