>Description:
I get an error due to including unistd.h and pthread.h in a .cpp file. Here is a small program which gives error on compiling with 'gcc'.

#include <unistd.h> 
#include <pthread.h> 
int main( void ) 
{ 
} 


The error returned is:
In file included from /usr/include/pthread.h:7,
                 from a.cpp:2,
/usr/include/sys/pthread.h:440: declaration of C function `int pthread_atfork(void (*)(), void (*)(), void (*)())' conflicts with
/usr/include/sys/unistd.h:187: previous declaration `int pthread_atfork(void (*)(...), void (*)(...), void (*)(...))' here

If I define _PTHREADS_DRAFT4 (check pthread.h), then the error is not shown but then I get the following error on using 'select' function call (not shown in this sample program)

a.cpp: In function `void RunApp()':
a.cpp:1294: passing `fd_set *' as argument 2 of `cma_select(int, int *, int *, int *, timeval *)'
*** Error exit code 1


I would appreciate if I can get an answer to this ASAP.

Thanks,

Anand Dua.
