           Summary: Incorrect C++ headers in the installed gcc
           Product: eCos
           Version: 3.0
          Platform: pc (i386 PC target)
        OS/Version: HostOS: Win NT/2k/XP
            Status: UNCONFIRMED
          Severity: normal
          Priority: normal
         Component: Other
        AssignedTo: jifl@ecoscentric.com
        ReportedBy: stano@meduna.org
         QAContact: ecos-bugs@ecos.sourceware.org
             Class: ---


The version of gcc installed for 386 under cygwin includes a version of C++
headers errorneously containing #include_next instead of #include.

$ i386-elf-gcc -v
Using built-in specs.
Target: i386-elf
Configured with: /gnutools/src/toolchains/gcc/gcc-4.3.2/configure -v
--target=i3
86-elf --prefix=/gnutools/builds/toolchains/i386-elf/tools --with-newlib
--with-
gnu-as --with-gnu-ld --enable-languages=c,c++ --disable-__cxa_atexit
--enable-th

--with-pkgversion='eCosCent
ric GNU tools 4.3.2-sw'
Thread model: single
gcc version 4.3.2 (eCosCentric GNU tools 4.3.2-sw)



This is a known gcc regression and shoudl be solved by upgrading to 4.3.3:

The fix for this issue is in various libstdc++ header files but libstdc++ is
not supported with eCos. Can you provide an example of how this issue might
affect eCos application developers?

I agree that it is not supported in stock eCos - I simply spotted the problem
experimenting with C++ code trying to figure what is missing. So no, I don't
have any real use case, it has just confused me and maybe it'll confuse a few
people more.

As of now this is no more an issue for us - I was able to compile own libstdc++
with rigth headers, supporting the features that we need.

If the libstdc++ headers should never be used, I'd suggest to remove them from
the toolchain distribution.
