  6. # DESCRIPTION
  7. #
  8. # This macro checks whether the specific compiler flag is supported.
  9. # The check is performing by appending FLAG-TO-TEST to the value of
  10. # VARIABLE-TO-EXTEND (LDFLAGS if not specified), then prepending result to
  11. # LDFLAGS (unless VARIABLE-TO-EXTEND is LDFLAGS), and then performing compile
  12. # and link test. If test succeed without warnings, then the flag is added to
  13. # VARIABLE-TO-EXTEND. Otherwise, if compile and link without test flag cannot
  14. # be done without any warning, the flag is considered to be unsuppoted.
