This is a problem I noticed trying to compile 1.1 
release on FreeBSD, but may apply to other systems too.
'Configure' script does not recognize threads library
on FreeBSD right. 


If you get linking errors like:

semaphore.o: In function `semaphore_init':
semaphore.o(.text+0x1a): undefined reference to `pthread_mutex_init'
semaphore.o(.text+0x40): undefined reference to `pthread_cond_init'
semaphore.o: In function `semaphore_destroy':
semaphore.o(.text+0x72): undefined reference to `pthread_mutex_destroy'
semaphore.o(.text+0x96): undefined reference to `pthread_cond_destroy'
...
cvoicecontrolkln2.o(.text+0x692): undefined reference to `pthread_join'
*** Error code 1

you have to set LDFLAGS variable to -pthread BEFORE
running ./configure. That is,

* in tcsh or csh type
	setenv LDFLAGS -pthread
	./configure --prefix=/usr/
	make
	make install

or:
* in bash or sh type
	LDFLAGS=-pthread
	export LDFLAGS
	./configure --prefix=/usr/
        make
        make install
