>Description:
Newer versions of gcc have started emitting error and warning messages
that have embedded newlines. This is most unfortunate as
it makes it difficult to filter out unwanted bogus warnings
using grep -v. An example of such error message is

/apps/gcc/std/include/g++-v3/bits/stl_threads.h: At global scope:
/apps/gcc/std/include/g++-v3/bits/stl_threads.h: In instantiation of `__gthread_mutex_t std::_Swap_lock_struct<0>::_S_swap_lock':
/apps/gcc/std/include/g++-v3/bits/stl_threads.h:122:   instantiated from here
/apps/gcc/std/include/g++-v3/bits/stl_threads.h:115: warning: aggregate has a 
   partly bracketed initializer
/apps/gcc/std/include/g++-v3/bits/stl_threads.h:115: warning: aggregate has a 
   partly bracketed initializer

As can be seen "partly bracketed initializer" is on the next
line, thus complicating ignoring it. World will be better
place if error messages remain on single line. Existing
presentation level tools, such as the emacs compilation mode
are better places to do line wrapping and other formatting.

The above snippet also demonstrates another annoying
"feature", namely that the standard template library
headers that are shipped with gcc-3.1 actually are not
warning clean (on SunOS-5.6 anyway).
>How-To-Repeat:
On SunOS-5.6 machine with gcc-3.1 compiled as follows

cd build-gcc
../gcc-3.1/configure --prefix=/apps/gcc/std
make bootstrap-lean

say

/apps/gcc/std/bin/g++ -Wall -c test.cc
>Fix:
1. Zap the damn newlines from error and warning messages
2. fix include/g++-v3/bits/stl_threads.h
>Release-Note:
>Audit-Trail:
>Unformatted:
 Configured with: ./configure --prefix=/apps/gcc/3.1
 Thread model: posix
 gcc version 3.1

 Thanks. So as Sun does not plan to fix it, then I guess it just
 wont get fixed. Oh well, its just another warning I need to grep -v
 out :-)

 This is in a FAQ somewhere, but:  it's specific to Solaris 2.6, and it's
 a problem in their thread header files.  Sun fixed the problem in later
 versions of Solaris but has no plans to backport the fix.  (It's just
 adding some punctuation, but oh well.)

 Thanks. That part understood. Now how about the warning from standard
 template library (include/g++-v3/bits/stl_threads.h)?

 Thanks for this tidbit, but how about the warning in the stl_threads.h?
