[Bug libstdc++/13837] New: libstdc++-v3: language c++ broken when cross compiling gcc for solaris (patch included)

binutils-2.14 configured as; 
../binutils-2.14/configure 
--prefix=/home/franke/cross-compile/sparc-sun-solaris 
--target=sparc-sun-solaris2.9

fails to build language c++. 
Problems: 
 1. libstdc++-v3/config/os/solaris/solaris2.7/ctype_noinline.h is not included. 
This results in build error at "ctype<char>::classic_table()". Solution: add 
solaris-case to $target switch in libstdc++-v3/configure.in (see below) 
 
 2. libstdc++-v3/configure.in has no $target switch for "*-solaris2*, therefore 
the default AC_DEFINES add HAVE_ACOSF etc to config.h, this will trigger an 
compile error at acos() (cmath) since solaris doesn't seem to have acosf()?! 
Adding the appropiate $target-switch fixes this (see below) 
 
 
Note on pathc below: the 
>      AC_DEFINE(HAVE_HYPOT) 
is taken from default target. I don't know whether it is needed or not ?!
