Make failed for kannel 1.4.4

Hi,

I am trying to install kannel gateway 1.4.4 on Debian jessie and getting
below error while make.

In file included from wmlscript/wslexer.c:72:0:
y.tab.h:262:5: error: conflicting types for ‘ws_yy_parse’
In file included from wmlscript/wslexer.c:70:0:
wmlscript/wsint.h:296:5: note: previous declaration of ‘ws_yy_parse’ was
here
 int ws_yy_parse(void *context);
     ^
Makefile:231: recipe for target 'wmlscript/wslexer.o' failed
make: *** [wmlscript/wslexer.o] Error 1

I have installed bison but no luck.

Please suggest me what can be the issue.

Regards,
Manas
