Jerome,

Thanks for the work. Few comments:

First, NAME_MAX was changed to FILENAME_MAX to match posix.  Also these
are defined in /usr/include/limits.h.  Doesn't bsd have this file? (I
recently fixed this problem for the Solaris port I did)  If it does,
then you shouldn't have to do any defining since this is now fixed in
current trunk.

I confirm, FILENAME_MAX is defined on FreeBSD (in stdio.h), so this part of my patch is actually not required. Do you want me to prepare a new one ?

Yes please.  Also the PATH_MAX variable should be defined somewhere in
your header files and doesn't need a definition in configure.ac.

I've attached a new version of the patch to this mail. You were right, PATH_MAX and NAME_MAX defines are not needed anymore. I've also tried to make the -ldl part a little bit less ugly.


I think the LDL part needs to be in some user defined flag in the
configure.ac.  The #if BSD with defining LDL is a bit hacky.  I'm not
sure where it should go however, so perhaps Jim or Fabio could comment.
If Jim or Fabio give that part the thumbs up, then this patch should be
good to go in.

the if defined semun wont work because unions are not defines.  That
entire code segment is wrong.  Can you try the attached patch on bsd for
me?

I think you misunderstood my problem: semun *is* already defined on FreeBSD, but the #if !defined(semun) doesn't work on my system (probably due to a GCC version difference ?) and the compiler ends up with a redefinition of semun.

Is there actually any system where semun is not already defined ?



Linux doesn't define it and Solaris doesn't even have a description of
the definition.  Do you have _SEM_SEMUN_UNDEFINED in your header files?
Or SEM_SEMUN_DEFINED?  That can be used to do an if defined test.

I haven't found any of them in the FreeBSD headers :/
