# com_bc.mak
# Make file to build com.lib and com_dbg.lib
#
# Prior to invoke make for the first time provide 'dbg' and 'rel'
# subdirectories in the current directory.
#
# Options from the make command line
# -D_DEBUG -- build debug version
# -DDISABLE_TIMING -- will disable the library to use the system timer
#   and	this will disable all the xxxTimed() functions from operation as well
# -DDISABLE_PREEMPTING -- will turn off the ability to be preempted the
#   process of handling COM IRQs.
# -DP386 -- will turn on '-3' option of the compiler and will push
#   all the 32bit registers in the IRQ wrappers.
#
# Output:
#   dbg\com.lib  -- in case /D_DEBUG specified on make command line.
#     This is debug version of the library. Contains plenty of extra
#     arguments checkings and internal functions control.
#   rel\com.lib -- This is release version of the library.
