1 7 Conditional Parts of Makefiles
1 ********************************

1 A "conditional" directive causes part of a makefile to be obeyed or
1 ignored depending on the values of variables.  Conditionals can compare
1 the value of one variable to another, or the value of a variable to a
1 constant string.  Conditionals control what 'make' actually "sees" in
1 the makefile, so they _cannot_ be used to control recipes at the time of
1 execution.
