Yes, but they are in the C++ libraries, which aren't automatically linked
by gcc when you compile (it only links the C libraries by default).  You
have to add '-lgpp' to the end of your compile command line to get
the standard C++ functions and classes linked.  The FAQ gives a lot
more details about this (including some other C++ libraries which contain
additional stuff).

If you have the inclination, and find you like DJGPP, I'd recommend
upgrading to version 2, which is a lot better than v1.*, fixes a lot of
bugs, and makes a lot of things easier in general.  You can get it
from any SimTel site (i.e.:  ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2*).
Be sure to read the 'readme.1st' file before downloading anything,
and definitely read the new FAQ (faq201b.zip) to see what's changed
from v1 to v2 (amongst other things).

BTW, I don't mean this to sound like a plug for v2 - it's just that v1.* is
obsolete and no longer supported by the DJGPP development team.
You can still get answers to your problems, of course, but you won't
see any new software or bug fixes for v1.  The book you bought has
been out for quite a while, so it's a bit out of date, but there's a new
DJGPP book project in the works which will contain the latest versions
of all software.  ;)
