Sorry my mistake. 2.95.1 is on RedHat 6.2 (glibc 2.1.3) and 2.96 on RedHat 7.3 
(2.2.5).

RedHat 6.2 with gcc 2.95.1
STLport is not installed and lives in its build directory. The test program is 
the following:

[alkise_at_starsky alkise]$ cat simple.cpp
#include <cstdlib>

int main(int argc, char** argv)
{
    return EXIT_SUCCESS;
}

[alkise_at_starsky alkise]$ g++ simple.cpp -o simple
[alkise_at_starsky alkise]$ g++  -isystem STLport-4.5.3/stlport   simple.cpp   -o 
simple -L STLport-4.5.3/lib -lstlport_gcc
STLport-4.5.3/lib/libstlport_gcc.so: undefined reference to 
`pthread_getspecific'
STLport-4.5.3/lib/libstlport_gcc.so: undefined reference to 
`pthread_key_create'
STLport-4.5.3/lib/libstlport_gcc.so: undefined reference to 
`pthread_setspecific'
collect2: ld returned 1 exit status
[alkise_at_starsky alkise]$ g++ -pthread -isystem STLport-4.5.3/stlport   
simple.cpp   -o simple -L STLport-4.5.3/lib -lstlport_gcc
[alkise_at_starsky alkise]$ nm STLport-4.5.3/lib/libstlport_gcc.so | grep pthread
         w pthread_create
         U pthread_getspecific
         U pthread_key_create
         w pthread_key_delete
         U pthread_mutex_destroy@@GLIBC_2.0
         U pthread_mutex_init@@GLIBC_2.0
         U pthread_mutex_lock@@GLIBC_2.0

         U pthread_mutex_unlock@@GLIBC_2.0
         w pthread_once
         U pthread_setspecific

RedHat 7.3 with gcc2.96
STLport is not installed and lives in its build directory. Using the same 
program:

[alkis_at_moro stlport]$ g++ simple.cpp -o simple
[alkis_at_moro stlport]$ g++  -isystem STLport-4.5.3/stlport   simple.cpp   -o 
simple -L STLport-4.5.3/lib -lstlport_gcc
STLport-4.5.3/lib/libstlport_gcc.so: undefined reference to 
`pthread_getspecific'
STLport-4.5.3/lib/libstlport_gcc.so: undefined reference to 
`pthread_key_create'
STLport-4.5.3/lib/libstlport_gcc.so: undefined reference to 
`pthread_setspecific'
collect2: ld returned 1 exit status
[alkis_at_moro stlport]$ g++ -pthread -isystem STLport-4.5.3/stlport   simple.cpp   
-o simple -L STLport-4.5.3/lib -lstlport_gcc
[alkis_at_moro stlport]$ nm STLport-4.5.3/lib/libstlport_gcc.so | grep pthread
         U pthread_getspecific
         U pthread_key_create
         U pthread_mutex_destroy@@GLIBC_2.0
         U pthread_mutex_init@@GLIBC_2.0
         U pthread_mutex_lock@@GLIBC_2.0
         U pthread_mutex_unlock@@GLIBC_2.0
         U pthread_setspecific

It both configurations libstlport_gcc.so ends up with undefined symbols to 
pthread specific functions.

Thanks. I will try that later today.
