Hi All,
I built gcc-cross from x86_64 host to armv7a target using gcc 4.5
r166342. I then tried to bitbake gcc (an armv7a-host, armv7a-target
native compiler) with the same revision and got build errors on libstdc++:

Making all in include

The issue has been discussed here:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40974
I tried the suggested fix by adding -nostdinc++ to PCHFLAGS in
libstdc++-v3/include/Makefile.am, but this appears not to propagate to
build.arm-angstrom-linux-gnueabi.arm-angstrom-linux-gnueabi/arm-angstrom-linux-gnueabi/libstdc++-v3/include/Makefile,
for OE reasons I don't understand. I tried "bitbake gcc -c compile"
once, got it to fail, changed
build.arm-angstrom-linux-gnueabi.arm-angstrom-linux-gnueabi/arm-angstrom-linux-gnueabi/libstdc++-v3/include/Makefile
directly, then reran "bitbake gcc -c compile", and it worked.
Perhaps someone wiser than I can turn this into a patch that works.
Best,
Matt
