Ok, this was not uclibc's fault, but a generic G++ (STL) cross compile
regression (in the upstream, GCC header files).

This should be addressed with r30044.

Just SVN updating the package/base/gcc and rebuilding just the cross
built gcc including STL should be enough:

./scripts/Build-Target  -cfg sparc64-glibc-cross  -job 1-gcc

your -cfg might vary

Unfortunately not. ERROR-LOG is attached. To confirm it was not a mixup
I also tried a complete build.

stdarg.h exists as:

root <at> kboxdev:/home/kbox/t2# find build/kbox-8.0-trunk-kbox-x86-cross/ -name 
stdarg.h
build/kbox-8.0-trunk-kbox-x86-cross/usr/include/c++/4.3.1/tr1/stdarg.h
build/kbox-8.0-trunk-kbox-x86-cross/usr/share/syslinux/com32/include/stdarg.h
build/kbox-8.0-trunk-kbox-x86-cross/usr/lib/gcc/i686-t2-linux-uclibc/4.3.1/include/stdarg.h
build/kbox-8.0-trunk-kbox-x86-cross/TOOLCHAIN/tools.cross/lib/gcc/i686-t2-linux-uclibc/4.3.1/include/stdarg.h

Ciao, MM

Apparently this still is an C++-issue unrelated to libusb. I have a custom
program packaged for T2 now that is written in C++. And it shows a similar
problem regarding stdarg.h not being found.

Is that a clue?

Not yet, but I noticed the same for uclibc based builds (with glibc C++ 
cross
building and libusb works, now, again in trunk:HEAD).

I'll continue to debug this issue later, maybe tonight. Patches welcome, 
though 

Yours,
