+Subject: [PATCH 18/39] export CPP
+
+The OE environment sets and exports CPP as being the target gcc. When
+building gcc-cross-canadian for a mingw targetted sdk, the following can be found
+in build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log:
+
+configure:3641: checking for _FILE_OFFSET_BITS value needed for large files
+configure:3666: gcc  -c -isystem/media/build1/poky/build/tmp/sysroots/x86_64-linux/usr/include -O2 -pipe  conftest.c >&5
+configure:3666: $? = 0
+configure:3698: result: no
+configure:3786: checking how to run the C preprocessor
+configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32
+configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
+configure:3876: $? = 0
+
+Note this is a *build* target (in build-x86_64-linux) so it should be
+using the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32
+headers are very different, using the wrong cpp is a real problem. It is leaking
+into configure through the CPP variable. Ultimately this leads to build
+failures related to not being able to include a process.h file for pem-unix.c.
+
+The fix is to ensure we export a sane CPP value into the build
+environment when using build targets. We could define a CPP_FOR_BUILD value which may be
+the version which needs to be upstreamed but for now, this fix is good enough to
+avoid the problem.
