#	2) Checking for various common build associated programs.
#	3) Determining the best build options for this platform.
#	4) Checking for certain common header files.
#	5) Checking for exports/global switch.
#	6) Importing OMI dependencies (header files, libraries, and binaries).
#       7) Checking for existence of various system libraries and routines.
