These types are problematic because they are typically declared in a non-standard way in U-Boot. For example, U-Boot uses 'long long' for int64_t even on a 64-bit machine whereas stdint.h uses 'long'. Similarly, U-Boot always uses 'long' for intptr_t whereas stdint.h mostly uses 'int'.
This simple test script runs a few toolchains on a few archs to check for warnings.
