GCC, however, does, and for Linux targets it installs stdint-wrap.h which for freestanding builds includes stdint-gcc.h rather than depending on the C library to provide the header. So as long as the kernel build uses -ffreestanding, it should not matter that the kernel doesn't have its own stdint.h. -- Joseph S. Myers jos...@codesourcery.com
