Stop in /bu/pkg/Python-2.5.1 (line 1111 of Makefile).

__BSD_VISIBLE is there (it wasn't there before and that's what was causing my original problem).
dnm at kili:/bu/pkg/Python-2.5.1$ grep _BSD_SOURCE pyconfig.h
dnm at kili:/bu/pkg/Python-2.5.1$ grep _BSD_VISIBLE pyconfig.h
#define __BSD_VISIBLE 1

I don't understand what's causing the problem, though:

/usr/include/unistd.h:
#if __XPG_VISIBLE >= 500
ssize_t  pread(int, void *, size_t, off_t);
ssize_t  pwrite(int, const void *, size_t, off_t);
int	 ttyname_r(int, char *, size_t)
	    __attribute__((__bounded__(__string__,2,3)));
#endif

#if __BSD_VISIBLE ||  __XPG_VISIBLE <= 500
/* Interfaces withdrawn by X/Open Issue 5 Version 0 */
void	 *brk(void *);
int	 chroot(const char *);
int	 getdtablesize(void);
int	 getpagesize(void);
char	*getpass(const char *);
void	*sbrk(int);
#endif

#if __POSIX_VISIBLE >= 200112 || __XPG_VISIBLE >= 420
int     lockf(int, int, off_t);
#endif
---

posixmodule.i:
ssize_t pread(int, void *, size_t, off_t);
ssize_t pwrite(int, const void *, size_t, off_t);
int ttyname_r(int, char *, size_t)
            __attribute__((__bounded__(__string__,2,3)));
# 188 "/usr/include/unistd.h" 3 4
int lockf(int, int, off_t);
---

Plus, I get lots of warnings that I didn't get using my patch.  Sample:

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes  -I. -I./Include  -DPy_BUILD_CORE  -c ./Modules/threadmodule.c -o Modules/threadmodule.o
In file included from Include/Python.h:57,
                 from Modules/threadmodule.c:5:
Include/pyport.h:520: warning: `struct winsize' declared inside parameter list
Include/pyport.h:520: warning: its scope is only this definition or declaration, which is probably not what you want
Include/pyport.h:521: warning: `struct winsize' declared inside parameter list

Here are the differences between the pyconfig.h with my patch and with yours:

dnm at kili:/bu/pkg/Python-2.5.1$ diff pyconfig.h pyconfig.h.martin
