Hi Alan,
This issue is not yet resolved, in the moment this cross-compiler issue looks

Yes, and that causes failures too. BUILD_CPPFLAGS is the culprit.

This code works fine so I don't think that we really need to do anything.

In gcc-interface/Makefile.in? I wasn't sure if it was really needed.
Out of curiosity, what do you set LDFLAGS to exactly?

Hi,
I'm having problems with that patch.
I try to start at X86_64-linux-gnu, and I want to get the GCC running on
arm-linux-gnueabihf.
I grabbed system headers and libraries from the target and put it in the prefix
path.
In the first step I do

Ok for mainline, up to the
When build != host, the build compiler obviously isn't the same as the
host compiler, but BUILD_CXXFLAGS is currently ALL_CXXFLAGS.
ALL_CXXFLAGS contains flags for which we run configure tests on the
host compiler, which may not work on the build compiler. I ran into
this with -Wno-narrowing. It
