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.
