Please consider the following lines of the document: ------------------------------------------------------------------ 5.7.3 Communicating Options to a Sub-make When make interprets the value of MAKEFLAGS (either from the environment or from a makefile), it first prepends a hyphen if the value does not already begin with one. Then it chops the value into words separated by blanks, and parses these words as if they were options given on the command line (except that ‘-C’, ‘-f’, ‘-h’, ‘-o’, ‘-W’, and their long- named versions are ignored; and there is no error for an invalid option). -------------------------------------------------------------------- I wonder if anybody can give an example how hyphen is added and the value is chopped.
