The gcc configure.ac script is using an obsolete form of the AC_CHECK_TYPE autoconf macro to check for caddr_t and ssize_t.
http://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/Obsolete-Macros.html#Obsolete-Macros This usage is causing a build failure for me when building a windows GCC using the mingw toolset. I would like to replace the obsolete autoconf macros with a 'proper' one. Tested with my mingw build and a MIPS targetted linux build. OK to checkin?
