Speex dev - Oct 2004 - speex headers and borland c++ builder (bcb)

hello,
I try to include the speex header to a bcb project. Speex headers are the
latest
one. My first problem was to use the lib file with bcb. I solved this issue
by
restructing the lib file. The second problem is to access the constant
called
"extern const SpeexMode speex_nb_mode;" through borland's c++
builder.
I could analyze the export table of the libspeex.dll. Unfortunately I could
not
find an entry for speex_nb_mode.
According to the manual I have to assign the address of this constant:

   /*Create a new encoder state in narrowband mode*/
   state = speex_encoder_init(&speex_nb_mode);

   /*Set the quality to 8 (15 kbps)*/

Could somebody explain how I can access this constant through borland's c++
builder?

kindly regards
Martin Roszak
