I sent an earlier patch to change how GCC configure was setting default
values of caddr_t and ssize_t. That patch fixed a build problem I had
when building GCC for Windows using the mingw tools but only because my
patch was wrong. Here is a new patch to fix the problem.
The problem was that crtstuff.c would not compile because it saw two
different (incompatible) definitions of caddr_t, one coming from
auto-host.h (set by the configure script) and one coming from the
sys/types.h system header file (part of glibc in my case).
Since crtstuff.c doesn't actually need or use caddr_t my patch
undef's it after including auto-host.h in the same way that
pid_t, rlim_t, ssize_t, and vfork are already undef'ed.
Note that there is a FIXME in crtstuff that says including auto-host
is wrong, but I don't have a fix for that larger issue.
Tested with my mingw build and a linux based mips toolchain.
OK to checkin?
