Implicit rules give an automatic definition of what a source file 
ending in .c (as an example) is supposed to do to produce the target 
file ending in .o.  If your makefile defines those rules then removing 
the implicit rules you don't need will have a definite performance 
impact.  If you're working in the MSYS or Cygwin shell you can always 
do ``alias make='make -r''' in your ~/.profile file to create your 
default value.
