[Buildroot] gcc 4.2.4 libstdc++ locale support

[Will Newton]

Hi,

I recently tried to build a toolchain with a combination of gcc 4.2.4,
C++ support and locale support but it failed to build.

The problem seems to be caused by some patches that are applied to
libstdc++ which are no longer compatible with the headers that current
uClibc is installing. I removed the patches and the build proceeds,
although I have no idea if any of the functionality is broken. The
patches are:

toolchain/gcc/4.2.4/200-uclibc-locale.patch
toolchain/gcc/4.2.4/203-uclibc-locale-no__x.patch
toolchain/gcc/4.2.4/204-uclibc-locale-wchar_fix.patch
toolchain/gcc/4.2.4/205-uclibc-locale-update.patch
toolchain/gcc/4.2.4/306-libstdc++-namespace.patch

Does anybody recall what they do or why they are needed?

Thanks,
