[nginx] svn commit: r4303 - trunk/auto

[maxim at nginx.com]

Author: maxim
Date: 2011-11-21 11:51:41 +0000 (Mon, 21 Nov 2011)
New Revision: 4303

Log:
o AIX 7 defines sys_nerr in errno.h, therefore <errno.h> included
in the sys_nerr test.

o When sys_nerr and _sys_nerr are missed on a particular platform
and our euristic for a maximum errno detection applied always
print the maximum errno number we reached instead of printing void.[*]

* patch from Maxim Dounin

This commit makes possible to build nginx on AIX 7.1.
