Common PLATFORM_HEADER Configuration#

Compiler and Platform specific definitions and typedefs common to all platforms.

platform-common.h provides PLATFORM_HEADER defaults and common definitions. This head should never be included directly, it should only be included by the specific PLATFORM_HEADER used by your platform.

See platform-common.h for source code.
