   I encountered a problem with 'make', but it could be just my ignorance...
   The thing is, I wrote a generic makefile for my small C++ project, like this:

   objs = file1.o file2.o file3.o

   .cc.o:
	   gcc -x c++ -c ›<

   main.exe: ›(objs)
	   gcc -o ›@ ›^

   file1.o: file1.cc file1.h
   file2.o: file2.cc file2.h
   file3.o: file3.cc file3.h


   Everything worked ok. But when I renamed all .cc files to .cpp and changed
   all appearances of .cc in the makefile to .cpp (including .cc.o: ), make
   always goes to the link step, even when there are no .o files at all.
   Just now some idea struck me -- this must have something to do with
   .SUFFIXES, but I thought .cpp was confirmed to be a valid C++ source
   file extension, thus make should recognize it. GCC itself recognizes it,
   though dumps .cc extension to cc1plus. Anyway, I'll read more make docs
   and try the .SUFFIXES stuff at home, but right now if the problem is different
   and someone knows the solution, please let me know.

If it is not the .SUFFIXES, look at your target commands.  In the mail meesage
there are spaces before the commands rather than a tab.  Is this a mailer
artifact or did your editor replace your tabs the last time you modified the
makefile?  Also I assume that the \233 are a mailer artifact and that you have
dollar signs ($) here.  Other than these and the possibility that .SUFFIXES
does not include .cpp your makefile looks OK to me.
