A patch for reg-stack.c

[H . J . Lu]

I believe this patch should fix

http://egcs.cygnus.com/ml/gcc-bugs/1999-10/msg00011.html

This bug only shows up if flag_pcc_struct_return is 1, which is the
default for Linux since the SVR4 ABI we are using requires the
structure/union be returned in memory regardless the size of
structure/union. I hope it will be fixed in gcc 2.95.2.

Thanks.
