#..  C Compiler definition
#
#    -ms                Generate code for the H8S chip.
#    -c                 Compile only
#    -0                 Optimize
#    -ffloat-store      Do not store floating point variables in registers
#                       and inhabit other options that might change whether
#                       floating point value is taken from register or
#                       memory.
#    -g3                The compiler debugging option, followed by the level.
#                       Level 3 included extra information.
#    -Wall              Issue warnings.
#    -r                 Elimates the use of built-in implicit rules.
#    -save-temps        Do not delete intermediate files
#    -mint32            Make int data 32 bits by default.
#    -malign-300        Align longs and floats on 2 byte boundaries.
