SunOS mars 5.8 Generic_108528-19 sun4u sparc SUNW,Ultra-250
Reading specs from /net/mars/exp/opt/gcc/lib/gcc-lib/sparc-sun-solaris2.8/3.2.3/specs

>Description:
source code is short:

typedef int I4;
I4 main() {
  return 0;
}

gcc main.c
gcc -Wall main.c
g++ main.c

These compiles fine.

g++ -Wall main.c

This fails.
