suspend other posix thread(s)

I just got this fancy application called `ags` see sourceforge.net/p/ags

During compilation I get the following error:

ags-ags_thread.o: In function `ags_thread_real_timelock':

/home/joel/ags-code/./src/ags/thread/ags_thread.c:1620: undefined reference to `pthread_suspend'

/home/joel/ags-code/./src/ags/thread/ags_thread.c:1660: undefined reference to `pthread_resume'

because the listed functions don't exist on debian GNU/Linux. How can I install the pthread library that provides those functions ...

    Now I write a module that uses pth instead of pthread library.

    The code looks like following:
    1. void
    2. ags_thread_suspend_handler(int sig)
    3. {
    4. #ifdef AGS_DEBUG
    5.   g_message("thread suspend\0");
    6. #endif
    7.  
    8.   if(ags_thread_self == NULL)
    9.     return;
    10.  
    11.   if ((AGS_THREAD_SUSPENDED & (g_atomic_int_get(&(ags_thread_self->flags)))) != 0) return;
    12.  
    13.   g_atomic_int_or(&(ags_thread_self->flags),
    14.                   AGS_THREAD_SUSPENDED);
    15.  
    16.   ags_thread_suspend(ags_thread_self);
    17.  
    18.   do sigsuspend(&(ags_thread_self->wait_mask)); while ((AGS_THREAD_SUSPENDED & (g_atomic_int_get(&(ags_thread_self->flags)))) != 0);
    19. }

    And is triggered like this: 
    1. pthread_kill(thread_id, AGS_THREAD_RESUME_SIG);
