As I just told you, I found something wrong:

>From the doc:

AC_DEFINE (variable, [value], [description]) Macro
Define C preprocessor variable variable. If value is given, set
variable to that value (verbatim), otherwise set it to 1.


cassis:~$ cat configure.ac 
AC_INIT                                                                         
                                                                             
AC_CONFIG_HEADERS(config.h)                                                     
                                                                             
AC_DEFINE(HAVE_PTHREAD,,[Define if we use pthread.h.])
AC_OUTPUT

cassis:~$ autoheader --version
autoheader (GNU Autoconf) 2.53c

cassis:~$ autoheader
autoheader: `config.h.in' is created

cassis:~$ ./configure 
configure: creating ./config.status
config.status: creating config.h


cassis:~$ cat config.h
/* config.h.  Generated by configure.  */
/* config.h.in.  Generated from configure.ac by autoheader.  */

/* Define if we use pthread.h. */
#define HAVE_PTHREAD 

/* Define to the address where bug reports for this package
 * should be sent. */
#define PACKAGE_BUGREPORT ""



HAVE_PTHREAD is not defined as it should if I follow the doc...
Doc problem, or something else ? If we have to explicitly specify
the "1", it would be good to know... I mean, it works just fine
if I explicitly specify AC_DEFINE(HAVE_PTHREAD,1,[Define if we
use pthread.h.])... But lots of packages out there use the first.

So ?
