           Summary: bug in ctype_inline.h header file (undefined __istype
                    will break compilation)
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ronald@landheer.com
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i386-unknown-freebsd4.7

When building from source (after having built the binutils, a bootstrap compiler
and a freshly ported Newlib) I configured with 
$ ../src/configure --prefix=/home/cross/tmp --target=i386-unknown-freebsd4.7
--with-newlib --disable-threads --disable-shared --enable-languages=c,c++,java 
$ make all install

Make produced a number of errors due to missing header files, but when examining
the ctype_inline.h header file from
i386-unknown-freebsd4.7/libstdc++-v3/include/i386-unknown-freebsd4.7/bits/ctype_inline.h,
in the build directory (which is a symlink to
libstdc++-v3/config/os/bsd/freebsd/ctype_inline.h in the source directory) I
found a rather odd bug:
      42       return _M_table[static_cast<unsigned char>(__c)] & __m;
      43     else
      44       return __istype(__c, __m);
      45   }
      46
Here, __istype is used, while it might not be defined and a couple of lines later:
      56         {
      57 #if defined (_CTYPE_S) || defined (__istype)
      58           *__vec = __maskrune (*__low, upper | lower | alpha | digit |
xdigit
      59                                | space | print | graph | cntrl | punct
| alnum);
      60 #else
      61           mask __m = 0;
Line 57 check whether __istype is defined or not, and in case it isn't, and
alternative piece of code is used, but not defining __istype will still break
the header file.
