Define "different platforms".  Do you need that Makfile to work with 
non-GNU Make and non-GNU C/C++ compilers?  If so, then your problem has 
no simple solution.  You will probably need some configuration script 
that will detect the flavor of Make and the compiler and build Makefiles 
from some template.

If you want it to be portable to GNU tools on other platforms, that's 
easier, but you still have problems with g++ vs gxx and libstdc++ vs 
libstdcxx.

The defaults do work for C++ projects, but they are correct for Unix 
systems, and nobody cared enough to make them tailored to DJGPP in the 
DJGPP port of Make.  (I guess most people don't use built-in rules too 
much, that's why nobody complained.)
