function Source_File_Is_Subunit (X : Source_File_Index) return Boolean;
-- This function determines if a source file represents a subunit. It
-- works by scanning for the first compilation unit token, and returning
-- True if it is the token SEPARATE. It will return False otherwise,
-- meaning that the file cannot possibly be a legal subunit. This
-- function does NOT do a complete parse of the file, or build a
-- tree. It is used in gnatmake to decide if a body without a spec
-- in a project file needs to be compiled or not.
