Description William Cohen 2002-09-04 18:22:24 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020513

Description of problem:
gcc gives a warning message about unsigned and signed compare on ia64 derry. I
originally thought this was same as bugzilla 57650, but I took a look at the
/usr/include/g++-3/sstream it it is identical to the one on an ia32 machine
which doesn't give the error message.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Compile the attached code with

 c++  -W -Wall -Wunused -Wmissing-prototypes -pipe -g -O2 -DCONST_POPT    -c -o
example.o example.cpp -save-temps


Actual Results:  c++: Warning: -pipe ignored since -save-temps specified
In file included from example.cpp:16:
/usr/include/g++-3/sstream: In method `streampos stringbuf::seekoff 
(long int, ios::seek_dir, int)':
/usr/include/g++-3/sstream:271: warning: comparison between signed and unsigned
integer expressions

Expected Results:  no warning

Additional info:

example.cpp ---------------------

#include <unistd.h>
#include <sys/wait.h>

#include <cerrno>
#include <sstream>
#include <iostream>

int main()
  return 0;
