Using STL containers in PDP++

[Martin =?iso-8859-15?q?Schaff=F6ner?= <schaffoe@ipe.et.uni-magdeburg.de>]

Hi there,

I am trying to add my own Environment to PDP++ for which I need something like 
a map. Being used to STL, I included <map> in enviro_extra.h, but get errors 
when making world, like this:

Compiling:  pdp_TA.cc on ko-pc15 in directory /usr/local/pdp++/src/pdp/LINUX 
in directory /usr/local/pdp++/src/pdp/LINUX at Fre Nov 14 13:42:38 CET 2003
g++ -fPIC -fno-implicit-templates -fno-exceptions -o pdp_TA.o 
-I/home/schaffoe/work/htk/HTKLib -I./src_include -I./src_include/pdp 
-I/usr/local/pdp++/include/LINUX -I/usr/local/iv/include     
-DHAVE_POSIX_SIGNALS=1 -DRETSIGTYPE=void -DLINUX  -c pdp_TA.cc
In file included from pdp_TA.cc:24:

   FreqEnv::UnSafeCopy(taBase*)':
src_include/pdp/enviro_extra.h:178: `TA_FreqEnv' undeclared (first use this
   function)

and a few more like this.

So, is it impossible to use STL-containers in PDP++ code? Or, how do I prevent 
these error messages?
