1The OE environment sets and exports CPP as being the target gcc. When building
2gcc-cross-canadian for a mingw targetted sdk, the following can be found in
3build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log:

14Note this is a *build* target (in build-x86_64-linux) so it should be using
15the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32 headers are
16very different, using the wrong cpp is a real problem. It is leaking into
17configure through the CPP variable. Ultimately this leads to build failures
18related to not being able to include a process.h file for pem-unix.c.
19
20The fix is to ensure we export a sane CPP value into the build environment when
21using build targets. We could define a CPP_FOR_BUILD value which may be the version
22which needs to be upstreamed but for now, this fix is good enough to avoid the
23problem.
