# Native C/C++ Compile Rules

#

#

# INCREMENTAL_BUILD: Record the #include file dependencies.

#

# NOTE: We build make include files with the suffix

#       $(DEPEND_SUFFIX) on every compilation. These are initially 

#       created as temp files just in case a ^C kills it in the middle.

#	Compiler is smart enough to handle ^C and not create the .o file, or

#	is supposed to be that smart, but the .$(DEPEND_SUFFIX) file 

#       creation here isn't.

#	These .$(DEPEND_SUFFIX) files are included by Library.gmk and 

#       Program.gmk, when they exist (Search for 'make dependencies').

#

  # Batch compiling might be faster if the compiler was smart about recognizing

  #   optimization opportunities available when all files are being compiled

  #   the same way. Unfortunately this is rare.

  #   Automatic pre-compiled headers (pch) might be a possibility so we

  #   add any auto pch options here.

  # So we save all the source files that have the same compile line as the

  #   first file. A normal compile pass is made after the batch compile

  #   to catch anything missed.

  # If the compilers had a -o option that allowed us to direct where to

  #   write the object files to, then we would not need to save the object

  #   file list or move them from the make directory to the build directory.
