Problem with gcc 3.0 and 3.0.1 and libstdc++

[Luke Mauldin <lukeskyfly at txk dot net>]

Hello, I have downloaded gcc 3.0 and I recently tried 3.0.1 snapshots from 
the CVS.  To build gcc I use the gcc_build script that comes with gcc and I 
input my configure options, etc...  When compiling C++ programs that make use 
of libstdc++ I get errors such as these:
g++ -DHAVE_CONFIG_H -I. -I. -I../../.. -I/usr/include 
-I/usr/lib/qt-2.3.0/include -I/usr/X11R6/include   -O2 -march=athlon 
-mcpu=athlon -D_REENTRANT -I/usr/include/sword -DQT_NO_ASCII_CAST  -O2 
-fno-exceptions -fno-check-new -Wall -pedantic -W -Wpointer-arith 
-Wmissing-prototypes -Wwrite-strings -Wno-long-long -fno-builtin -O2 
-march=athlon -mcpu=athlon -c cswordmodulesearch.cpp

                 from /usr/include/g++-v3/bits/std_string.h:41,
                 from /usr/include/g++-v3/string:31,
                 from /usr/include/sword/swmgr.h:40,

                 from cswordmoduleinfo.h:23,
                 from cswordmodulesearch.cpp:20:
/usr/include/g++-v3/bits/std_cstring.h:40:25: string.h: No such file or 
directory

I look in /usr/include/g++-v3/bits/std_cstring.h here are lines 39 and 40.
#pragma GCC system_header
#include_next <string.h>

If I replace <string.h> with </usr/include/string.h>  everything works fine.  
This is not just a problem with std_cstring.h, it is a problem in every file 
in /usr/include/g++-v3/bits/  In order to get programs to compile properly I 
have to replace just #include_next <****.h> with #include_next 
</usr/include****.h>  I have been following the mailing lists for the last 
several months, and I have not seen these problem reported before.  Is it 
something I am doing wrong, or is it a problem with gcc?
