Why is gcc going to default to "GNU dialect of ISO C99?"

If you wish to use a compiler that ad hers to ISO C99, then you should
use the c99 program as per POSIX 1003.1 2004; that is the proper and
standard compliant way to invoke a ISO C99 compiler.  What the gcc
program will do by default is set by the GNU project, the g after all
stands for GNU, not ISO or POSIX.
