Summary: configure problem on HP-UX 11.11

Initial Comment:
Python 2.4c1 has this problem (but if I recall, so did 2.3.3)_ 
 
Using gcc 3.3.3 to build on HP-UX 11.11, the  
configure out of the box is a bit off, resulting in a failed build, due 
to missing thread symbols: 
 
/usr/ccs/bin/ld: Unsatisfied symbols: 
   PyThread_acquire_lock (first referenced in 
libpython2.4.a(import.o)) (code) 
   PyThread_exit_thread (first referenced in 
libpython2.4.a(threadmodule.o)) (code) 
   PyThread_allocate_lock (first referenced in 
libpython2.4.a(import.o)) (code) 
   PyThread_free_lock (first referenced in 
libpython2.4.a(threadmodule.o)) (code) 
   PyThread_start_new_thread (first referenced in 
libpython2.4.a(threadmodule.o)) (code) 
   PyThread_release_lock (first referenced in 
libpython2.4.a(import.o)) (code) 
   PyThread_get_thread_ident (first referenced in 
libpython2.4.a(import.o)) (code) 
   PyThread__init_thread (first referenced in 
libpython2.4.a(thread.o)) (code) 
collect2: ld returned 1 exit status 
 
A workaround is to manually edit pyconfig.h, adding  
#define _POSIX_THREADS 
 
(The reason it is not picked up is that unistd.h on HP-UX has this 
comment: 
 
/************************************************************************ 
 * The following defines are specified in the standard, but are not 
yet 
 * implemented: 
 * 
 *        _POSIX_THREADS                     can't be defined until all 
 *                                           features are implemented 
) 
 
The implementation seems however to be sufficiently complete 
to permit compiling and running Python with _POSIX_THREADS. 
 
While I'm editing pyconfig.h, I also comment out 
_POSIX_C_SOURCE definition, as it will result in lots of 
compilation warnings, of the style: 
 
gcc -pthread -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall 
-Wstrict-prototypes -I. -I../Python-2.4c1/Include  
-DPy_BUILD_CORE -o 
Objects/frameobject.o ../Python-2.4c1/Objects/frameobject.c 
In file included from ../Python-2.4c1/Include/Python.h:8, 
                 from ../Python-2.4c1/Objects/frameobject.c:4: 
pyconfig.h:835:1: warning: "_POSIX_C_SOURCE" redefined 
<command line>:6:1: warning: this is the location of the 
previous definition 
 
------------ 
 
So, to recapitulate:  After configure, add  
#define _POSIX_THREADS 
and comment out 
#define _POSIX_C_SOURCE 200112L 
 
That will give you a Python working rather well,  
with "make test" producing: 
 
251 tests OK.

    test_pty

_POSIX_C_SOURCE appears to come from the gcc driver, along with a 
few other macros. 
 
If I add "-v" to compilation, the output expands to:

Can you find out why gcc says that "_POSIX_C_SOURCE" is
defined on the command line? On the command line you
provide, it isn't.
