Background: Been using C since BDS C running on CP/M. Been using 
DJGPP C since version 1.something. New to C++. I got a copy of above 
book (author is Steve Oualline, publisher is O'Reilly & Associates) 
as a present. I've downloaded the source (DOS version) examples from 
the O'Reilly web site.

Problem:
DOS version has files with .cpp extensions, and makefiles for Borland 
C++, Turbo C++, MS, generic Unix, and "GNU".
The "GNU" makefiles are closest to what's required for DJGPP. Here's 
a typical makefile.gnu (minus comments) for a single source-file 
example:

=== start of makefile.gnu
CC=g++
CFLAGS=-g -Wall
all: array

array: array.cc
        $(CC) $(CFLAGS) -o array array.cc

clean:
        rm array
=== end of makefile.gnu

Some changes would be needed:
(1) (a) CC = gcc, CFLAGS += -lgpp -lstdcx 
	[**** FAQ BUG *** see below]
    OR
    (b) CC = gxx
(2) File extension conflict (files are called foo.cpp, makefile uses 
foo.cc)

Before I launch into awk / perl / shell-utilities to lash up a bulk 
fix-up, I have some questions:

(1) Has anyone already done this?
(2) Which is a "better" naming convention to use for C++ source 
files generally, foo.cc or foo.cpp?
(3) Has Q2 just started a holy war?
(4) As most of the examples involve a single source file, I think 
I'll just write a mak.bat that compiles & links the %1.cc or %1.cpp 
file, and fiddle the remaining makefiles by hand; this will save some 
disk space; any comments?

Here's the (very minor) FAQ bug:

> The Standard C++ Template classes are in `libstdcx.a' (it's called 
> `libstdc++.a' on Unix); append `-lstdcxx.'
                                         ^

Happy New Year to all,
