SOURCES

Specifies a list of directories, each separated by at least one -space, which should be searched for assembler include files (.inc), -and possibly C/C++ header files (.h) to be translated -into assembler syntax.

Each entry in this list is relative to the -directory in which the platform-specific makefile resides.
