view src/os/unix/ngx_sunpro_atomic_sparc64.h @ 4354:cdb2e95bd3d0 stable-1.0
Merge of r4231, r4300, r4303, r4304:
Configure/build changes and fixes:
*) Revamped "configure --help" text.
*) FreeBSD 10-current has recently gotten POSIX_FADV_* macros.
A fix for the broken build applied.
*) AIX 7 defines sys_nerr in errno.h, therefore <errno.h> included
in the sys_nerr test.
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.
This makes possible to build nginx on AIX 7.1.
*) Made it possible to build/install from the SVN checkout.
