           Summary: <iostream> causes transform() to not compile with
                    tolower()
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: davidg@flash.net
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.3/specs
Configured with: ../gcc-3.3/configure --enable-languages=c,c++
Thread model: posix
gcc version 3.3

******
The code below causes the following error *only* if <iostream> is included.

I got the same error using g++ v3.2.2

The code compiled fine under an older version of g++ (sorry I don't have the 
number)
