Bug Report for GCC:
-------------------
Problem : In the short program below, gcc 1.32 complains about requesting

2.) Input Program :
-----------------
main ( ) {
register int foo[10];
*(foo + 2) = 10; /* a warning is given here, but why? */
foo[2] = 10; /* same thing, but no warning */
}
3.) Command Used : gcc
----------------
4.) Files used :

md -> sparc.md
config.h -> xm-sunos4.h
