#
#   Compiler flags
#   -A,     - Sets ANSI-compliant mode. -nA disables all ANSI features. This
#             is not the same as strict ansi, so don't use it.
#   -c      - Produces an object file but not an executable file.
#   -Feo    - Writes diagnostic messages to standard output.
#   -Fsm    - Includes high-level source code as comments in the assembly output file.
#   -g      - Generates debugging information.
#   -H      - Saves assembly file.
#   -Og     - Enables global-flow optimizations. (-nOg is default)
#   -Ol     - Enables local optimizations.
#   -OR     - Allocates heavily used variables to registers.
#   -Ob     - Performs optimizations that assume that global memory objects are not changed through aliases.
#             Do not use. More troible than its worth.
#   -Oe     - Generates only one exit (return) from a function.
#   -Or     - Enables instruction scheduling optimization.
#   -Os     - Optimizes in favor of code size rather than execution time.
#   -v      - Detects and issues warnings for features in the source files that can cause problems.
#   -x      - Enables Microtec Compiler extensions to C and C++. (default)
#   -Kf     - Generate stack frame for all functions.
#
#
#   The following options are specified within $(mri_compiler_flags) and are considered global
#   -pxxxx  - Produces code for a specified processor.
#   -mac    - Take advantage of the ColdFire MAC unit.
#   -mdiv   - Take advantage of the ColdFire DIV unit.
#   -Gf     - Generates fully qualified path names for input files.
#   -KhA5   - Reserves one or more registers.
#   -Ku     - Treats plain char variables as unsigned.
#   -Mcp    - Use PC-relative addressing for all code references.
#   -Md5    - Use register-relative addressing for all static data references.
#   -Ml     - Use 32-bit displacements for register An-relative or PC-relative addressing.
#   -nQ     - The -nQ option does not suppress any messages.
#   -nze    - Disable C++ exception handling.
#   -Wa,-fNOPCR     - Passes options to the assembler.
#   -Xp     - Allocates space for global variables that have not been explicitly initialized.
#   -zc     - Allows // comments in C code.

#   Before executing the compiler we must
#   1) Create a command file to contain all the command line arguments
#   2) Work around a bug in the MicroTex 68K compiler
#      The bug is that the compiler uses temp files, but it does not
#      ensure that the files are empty before it uses them.
#      The work around is to generate the temp files in a known directory
#      and to delete all temp files before we compile.
