Solaris 7, Sun SC5.0 compiler
>Description:
Upon standard install, during the "make && make install" phase, compilation of locale.cc resulted in an illegal conversion error within ctype.cc given the following:

libstdc++-2.90.7/config/solaris/bits/ctype_base.h:
  typedef long* __to_type;

libstdc++-2.90.7/config/solaris/ctype.cc:
  ctype_base::__to_type const& ctype<char>::_S_toupper = __trans_upper;

/usr/include/ctype.h:
  extern int* __trans_upper;
>How-To-Repeat:
mkdir bld-libstdc++
cd bld-libstdc++
../libstdc++-2.90.7/configure --prefix=/usr/local/gnu-new-libstdc++ --enable-namespaces
make && make install
>Fix:
In libstdc++-2.90.7/config/solaris/bits/ctype_base.h, replace this:
  typedef long* __to_type;

with this:
  typedef int* __to_type;
