Not entirely... you could use Make variables and conditionals to create
a makefile that would work one way under DOS and another way under
Unix, based on the definition of a variable.

However, since so much of what Make does is dependent on the
shell program that it uses, there is no way to make the commands
themselves 100% portable.  Quite simply, Unix sh works differently
than DOS command.com, and Make can only use what it is given to
work with.
