It's most likely because you aren't telling djgpp that you are trying to
compile a C++ program so it doesn't know to look in the C++ paths for
the headers.  Check the following things:

1) Your program must have a C++ suffix ('.cc' or '.cpp') to be
recognized as C++.  You _can_ use .C (upper case) but since DOS is
case-insensitive you have to specifically tell gcc that it's a C++
program by making it upper case on the command line.  (i.e., "gcc foo.c"
is different from "gcc foo.C")

2) Try using 'gxx' instead of 'gcc' to compile your program.  If you
don't have 'gxx' then see #3 below.

3) Make sure that you downloaded the C++ packages for djgpp as well as
just the C ones.  The C++ packages are gpp272b.zip and lgp271b.zip in
the v2gnu directory of SimTel.  (NOTE:  Some files were missing from
these packages in the original v2 distribution.  Make sure your copies
of the zipfiles are dated Feb. 22 or later, and if not, get new ones.)

4) Make sure the C++ headers are in the right place.  They don't go in
the standard include directory; look for the /lang/cxx directory in your
djgpp installation.  If you have installed the C++ packages and this
directory doesn't exist, make sure you used '-d' when you unzipped the
packages.

5) If all else fails, post details of your system configuration here on
the newsgroup, as outlined in section 6.12 of the FAQ.  (command.com,
autoexec.bat, system environment (output of DOS 'set' command), the
output of 'go32-v2', and particularly the contents of your 'djgpp.env'
file)

HTH!

John
