[issue4026] fcntl extension fails to build on AIX 6.1

[Sébastien Sablé]

Sébastien Sablé <sable at users.sourceforge.net> added the comment:

[rant: grrr, AIX is really a crappy platform; no consistency between releases; there are dozens of obvious bugs like that... anyway...]

The fact that there is no 64 bits objects in libbsd.a on AIX 6.1 is a documented bug:
http://www-01.ibm.com/support/docview.wss?uid=isg1IZ45155

They recommend to install patch APAR IZ45155.

I suppose there is nothing more we can do if the function is not available on the system. Maybe we could display a warning or error message and suggest to upgrade to a more recent patchlevel if we are on AIX and flock cannot be found?

Though if the installation is relatively up to date, there should be no problem.
