Problem with libspeechd.h

[Lukasz Grabowski]

Hello,
I'm writing a small C++ application in which libspeechd.h is included
in voice.h, and voice.h is included in a main source file sradio.cpp;
g++ fails to build:
===========
luke at rokkanon:/testy/sradio$ make
g++    -c -o shuffler.o shuffler.cpp
g++    -c -o megahstack.o megahstack.cpp
g++    -c -o osdx.o osdx.cpp
g++    -c -o voice.o voice.cpp
g++    -c -o sradio.o sradio.cpp
sradio.cpp: In function ?int lirc(char*, char*, MegahStack*)?:

===========
I know there was a similar problem reported on this list some time ago.
However, my libspeechd.h _does_ include
#ifndef _LIBSPEECHD_H
#define _LIBSPEECHD_H
...
#endif /* ifndef _LIBSPEECHD_H */

I even checked if I didn't define spd_debug in my program, but
apparently I didn't. Thus it seems to me to be a problem with
libspeechd. However, I'm an inexperienced programmer, so maybe you
could tell me what else could be wrong with _my_ code.

If I merge code from voice.cpp with sradio.cpp,
everything builds fine.

Best,
