pthread_mutexattr_settype() ... g++ 2.96 ... won't work

[Andrey]

   Hi,

   Here's the problem. I have a call to
pthread_mutexattr_settype() in C++ code, and compile
it with g++ 2.96. It doesn't see the function, when I
look into pthread.h, it is #defined __USE_UNIX98,
which is not defined.

   What is interesting, I can compile the very same
code with g++ 3.2.2. Also, I can compile the C code
with the pthread_mutexattr_settype() function using
gcc. ALSO :), when I put this into simple C program

#ifndef __USE_UNIX98
#error blah
#endif
#include <pthread.h>
. . . 

pthread_mutexattr_settype(...)

and compile it with gcc, it bails out with the error!
How come?

Anyway, the main question is -- I need to compile C++
code with g++ 2.96 and somehow initialize a recursive
mutex. Any ideas? Thanks!
