This is quoted from http://gcc.gnu.org/gcc-3.4/changes.html : # The cast-as-lvalue extension has been removed for C++ and deprecated for C and Objective-C. In particular, code like this: char *p; ((int *) p)++; is no longer accepted for C++ and will not be accepted for C and Objective-C in a future version. Unfortunately I don't know the proper fix, but I'm hoping I'll get an answer to that question tomorrow in the gcc-help mailing list.
How about: char *p; ... int *q = (int *) p; q++; p = (char *) q;That would have the same net effect and is accepted by gcc 4.2.3, which does not accept the original construct.
