'v2/readme.1st' tells you what you need to do to compile C++ programs. 
The required packages, in addition to the basic DJGPP packages
(v2/djdev201.zip, v2gnu/bnu281b.zip, v2gnu/gcc2721b.zip), are
'v2gnu/gpp2721b.zip' and 'v2gnu/lgp271b.zip'.  If you have all of these,
then you should have unzipped them all in the SAME way, from the SAME
directory, making sure to preserve the directory structure in the
zipfiles (default for unzip386, '-d' switch with pkunzip).  When you are
done you should have a directory structure that looks like this: 
(substitute your own directory for the root djgpp dir)

djgpp
  |-- bin
  |-- include
  |-- info
  |-- lang
  |-- lib
  |-- manifest
  |-- temp
  |-- zoneinfo

This is the correct directory structure for a DJGPP installation.  Once
you have done this, you must make the two autoexec.bat changes listed in
'readme.1st':  add the 'bin' directory to your PATH, and set the DJGPP
environment variable.  Reboot so the changes will take effect, and you
should be able to compile programs.

Instructions for compilation are also in 'readme.1st'.  Basically, you
use 'gcc' to compile C programs, and 'gxx' to compile C++ programs. 
gcc/gxx has a plethora of options that you can read about using the
online Info documentation reader in v2gnu/txi390b.zip.
